Understanding Radioactive Waste
Nuclear, or radioactive waste is the waste product of nuclear reactors, fuel processing plants, research facilities and hospitals, and is also produced when nuclear reactors and facilities are dismantled.
Radioactive waste is differentiated into high-level and low-level radioactive waste. While high-level waste is the spent fuel detached from nuclear reactors, low-level waste is generated from other scientific, industrial and commercial uses of radioactive materials (USNRC, 2015).
India however, also includes a third category called intermediate-level radioactive waste, which require shielding for disposal but little or no heat protection. Intermediate-level radioactive wastes are disposed in a similar manner to high-level radioactive waste and are concentrated and fixed in cement. These qualities are delineated according to the radioactive content present in the waste and its half-life i.e. the time consumed by the waste in losing half of its radioactivity.
High-level radioactive waste comprises the fuel which is used up in a nuclear reactor for generating electricity, usually uranium, which is called spent fuel – fuel that is no longer efficient for producing electricity. Nuclear energy produced through the process of nuclear fission produces fission products such as radioactive isotopes of strontium-90 and cesium-137, which are lighter elements that provide the penetrating radiation and the hottest elements in radioactive waste.
Also plutonium, a heavier element produced during fission by the capture of neutrons by uranium atoms and also other trans-uranic elements heavier than uranium do not possess the same heat and penetrative capacity as lighter elements but however, take much longer to decay and can be a radioactive hazard in nuclear waste much longer than 1,000 years (USNRC, 2015).
Management of radioactive waste
Management of radioactive waste is dependent on its properties, which can be radioactive, chemical, or physical properties.
High-level radioactive wastes are made up of complex amalgamations of radionuclides (radioactive forms of elements) of about 30 to 40 different elements. Most of these radionuclides are toxic and emit radioactive particles like alpha, beta or gamma rays during their decay. The disposal of high-level radioactive wastes requires their storage i.e. containment and concentration.
There are different time periods for which high-level radioactive wastes need to be isolated and stored, depending on the amount of time the radioactive wastes take to decay i.e. reach a level roughly equal to naturally occurring radiation levels i.e. to that of uranium ore for example.
The time period required can sometimes extend up to more than 1,00,000 years and as this makes storage difficult. Technologies are being developed in an effort to reduce the time period to about 1,000 to 10,000 years. In contemporary times, however, the most potent storage solution is part-geological – the immobilization of radioactive wastes.
Mechanism of immobilization
The immobilization of radioactive wastes is based on the multiple barrier system (MBS) concept, which is composed of an engineered barrier system and a natural barrier system. The engineered barrier system, with cooled off radioactive wastes contained inside a stainless steel canisters placed inside a drilled hole underground that is surrounded by rocks such as granite or basalt, which act as a natural barrier.
There are other storage methods such as the dry cask method where the stainless steel canisters containing nuclear waste are surrounded by concrete after the spent fuel is cooled for about 5 years.
However, the dry cask method is not as safe as the geological method and cannot be called a permanent method of storage of radioactive wastes. Some other methods of disposal of radioactive wastes include reprocessing, transmutation and space disposal.
Geological disposal of radioactive wastes is not present however, in many countries and some of the countries that have implemented immobilized geological disposal include Sweden, France, Finland and India (in Tarapur and Trombay).
Low-level radioactive waste comprises of substances that are contaminated with radioactive material or those that have become radioactive due to exposure to radioactivity. The amount of radioactivity in low-level radioactive waste can vary from base levels found naturally to the amount of radioactivity found in nuclear reactors. Low-level radioactive wastes are conventionally stored on-site until it decays and then can be disposed off harmlessly or it can also be shipped to a secure location (USNRC, 2015).
Health Effects
The nature and severity of the health effects of radiation exposure depends upon the amount of radiation and the time for which one is exposed to radiation. Radiation exposure in relation to human health can be chronic or acute exposure.
Continuous or intermittent exposure to radiation over a long period of time leads to chronic exposure. In chronic exposure the health effects are observed a certain time period after exposure to radiation, and most commonly leads to cancer.
Other health effects include genetic changes, cataracts, tumors, etc.
Acute exposure occurs when large parts of the human body are exposed to large amounts of radiation and can occur one time or multiple times over intervals of time (USEPA, 2017). Acute exposure leads to radiation sickness, which is a collection of health effects taking effect within 24 hours of acute exposure to radioactivity involving mainly cellular degradation and its various symptoms.
Smaller exposures can lead to gastrointestinal effects, nausea, vomiting and reduced blood counts. A larger exposure can lead to neurological effects and even death. As the cells of pregnant women and foetuses divide rapidly, providing greater opportunity for radiation to spread and cause cell damage, they are particularly at risk of exposure to radiation.
Among power plant accidents and radioactive contamination risks the most recent disaster in memory is the Fukushima disaster that occurred after the earthquake and tsunami that rocked Japan in 2011.
The disaster led to explosions and melting of fuel rods at the power plants and although there weren’t as many casualties as in the Chernobyl disaster of 1986, the long term effects and cancer-related death are still taking place.
Most of the nuclear power plant disasters in recent history have taken place in Europe and the US, with the Fleurus (Belgium 2006), Forsmark (Sweden 2006), Erwin (US 2006), Sellafield (UK 2005) Braidwood (US 2005) and Paks (Hungary 2003) disasters.
The most severe disasters in terms of casualties and damage to the environment are said to be the Chernobyl (erstwhile USSR 1986), Kyshtym (erstwhile USSR 1957), Windscale (UK 1957) and Three Mile Island (US 1979) disasters with the former two leading to a severe release of radioactivity with severe health and environmental consequences while the latter two had a more limited release of radioactivity (The Guardian, 2011) but led to numerous deaths due to inadequate containment.
Policy Regime on Radioactive Wastes
In terms of the governance of radioactive wastes, the first point is that radioactive wastes can only be handled by trained personnel who are specialists. They mostly work in the 446 nuclear power plants operational in the world that produce radioactive wastes (IAEA, 2017).
However, other than the organizational aspect, the only legal policy to implement safety standards in managing radioactive wastes internationally is the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.
While the International Atomic Energy Agency (IAEA) manages nuclear safety on the international arena, in India the Atomic Energy Regulatory Board (AERB) formulates policies and lays down safety standards concerning nuclear energy. The AERB exercises regulation by laying down guidelines and a licensing system based on stage-based evaluation, which is the bulwark of India’s nuclear safety programme.
As per the AERB, there are 20 operating nuclear plants in India that includes 4 units of the Tarapur nuclear power station, 6 units of the Rajasthan nuclear power station, 2 units of the Kalpakkam nuclear power station in Tamil Nadu, 2 units of the Narora nuclear power station in UP, 2 units of the Kakrapar nuclear power station in Gujarat and 4 units of the Kaiga nuclear power station in Karnataka (AERB, 2013).
AERB’s involvement in India’s nuclear safety programme includes reactor design policies, radiation exposure targets, radioactive waste management, and preparedness for nuclear emergencies. The most popular storage method is vitrification (converting radioactive waste to glass-like solid cakes) in India, followed by storage in steel canisters. There is a necessity in India for more geological storage facilities like those in Tarapur and Trombay.
The instrument for the IAEA internationally is the Joint Convention that seeks to achieve nuclear safety through an international collaborative approach based on the sharing of expertise on radioactive wastes and spent fuel management.
The Convention fixes international safety standards and measures to ensure nuclear safety based on agreements between stakeholders and it strives to achieve national arrangements in individual countries based on the standards agreed upon in the convention. The Convention also includes clauses that facilitate individual countries with improper infrastructures to receive international assistance in case of a lack of resources. The Convention applies both to countries with nuclear power programmes and those using radiation sources for industrial and commercial purposes (IAEA, 2011).
U.C. Mishra of the AERB, writing while working for the Bhabha Atomic Research Centre (BARC) says that, “The preferred approach in our country in this perspective [environment] is concentration and contamination of radionuclides rather than their dilution and dispersion into the environment” (U.C. Mishra, BARC, 2011). One only needs to remember the Chernobyl, Fukushima and Three Mile Island disasters to understand the horrific impacts radiation discharges can have on the environment and health.
In such a scenario, a proper method and discipline of storing radioactive wastes, coupled with a regulative infrastructure that supports nuclear safety and an international regime that facilitates and ensures the presence of safety standards and infrastructure in case of deficiencies in individual countries is imperative.
The first step towards this would be a foolproof method of containing radioactive wastes, and the geological immobilization of radioactive wastes, seen as among the most effective techniques, or a similarly effective storage technology effectively implemented worldwide would be a giant step forward in this regard.

Steve Ovett, the famous British middle-distance athlete, won the 800-metres gold medal at the Moscow Olympics of 1980. Just a few days later, he was about to win a 5,000-metres race at London’s Crystal Palace. Known for his burst of acceleration on the home stretch, he had supreme confidence in his ability to out-sprint rivals. With the final 100 metres remaining,
[wptelegram-join-channel link=”https://t.me/s/upsctree” text=”Join @upsctree on Telegram”]Ovett waved to the crowd and raised a hand in triumph. But he had celebrated a bit too early. At the finishing line, Ireland’s John Treacy edged past Ovett. For those few moments, Ovett had lost his sense of reality and ignored the possibility of a negative event.
This analogy works well for the India story and our policy failures , including during the ongoing covid pandemic. While we have never been as well prepared or had significant successes in terms of growth stability as Ovett did in his illustrious running career, we tend to celebrate too early. Indeed, we have done so many times before.
It is as if we’re convinced that India is destined for greater heights, come what may, and so we never run through the finish line. Do we and our policymakers suffer from a collective optimism bias, which, as the Nobel Prize winner Daniel Kahneman once wrote, “may well be the most significant of the cognitive biases”? The optimism bias arises from mistaken beliefs which form expectations that are better than the reality. It makes us underestimate chances of a negative outcome and ignore warnings repeatedly.
The Indian economy had a dream run for five years from 2003-04 to 2007-08, with an average annual growth rate of around 9%. Many believed that India was on its way to clocking consistent double-digit growth and comparisons with China were rife. It was conveniently overlooked that this output expansion had come mainly came from a few sectors: automobiles, telecom and business services.
Indians were made to believe that we could sprint without high-quality education, healthcare, infrastructure or banking sectors, which form the backbone of any stable economy. The plan was to build them as we went along, but then in the euphoria of short-term success, it got lost.
India’s exports of goods grew from $20 billion in 1990-91 to over $310 billion in 2019-20. Looking at these absolute figures it would seem as if India has arrived on the world stage. However, India’s share of global trade has moved up only marginally. Even now, the country accounts for less than 2% of the world’s goods exports.
More importantly, hidden behind this performance was the role played by one sector that should have never made it to India’s list of exports—refined petroleum. The share of refined petroleum exports in India’s goods exports increased from 1.4% in 1996-97 to over 18% in 2011-12.
An import-intensive sector with low labour intensity, exports of refined petroleum zoomed because of the then policy regime of a retail price ceiling on petroleum products in the domestic market. While we have done well in the export of services, our share is still less than 4% of world exports.
India seemed to emerge from the 2008 global financial crisis relatively unscathed. But, a temporary demand push had played a role in the revival—the incomes of many households, both rural and urban, had shot up. Fiscal stimulus to the rural economy and implementation of the Sixth Pay Commission scales had led to the salaries of around 20% of organized-sector employees jumping up. We celebrated, but once again, neither did we resolve the crisis brewing elsewhere in India’s banking sector, nor did we improve our capacity for healthcare or quality education.
Employment saw little economy-wide growth in our boom years. Manufacturing jobs, if anything, shrank. But we continued to celebrate. Youth flocked to low-productivity service-sector jobs, such as those in hotels and restaurants, security and other services. The dependence on such jobs on one hand and high-skilled services on the other was bound to make Indian society more unequal.
And then, there is agriculture, an elephant in the room. If and when farm-sector reforms get implemented, celebrations would once again be premature. The vast majority of India’s farmers have small plots of land, and though these farms are at least as productive as larger ones, net absolute incomes from small plots can only be meagre.
A further rise in farm productivity and consequent increase in supply, if not matched by a demand rise, especially with access to export markets, would result in downward pressure on market prices for farm produce and a further decline in the net incomes of small farmers.
We should learn from what John Treacy did right. He didn’t give up, and pushed for the finish line like it was his only chance at winning. Treacy had years of long-distance practice. The same goes for our economy. A long grind is required to build up its base before we can win and celebrate. And Ovett did not blame anyone for his loss. We play the blame game. Everyone else, right from China and the US to ‘greedy corporates’, seems to be responsible for our failures.
We have lowered absolute poverty levels and had technology-based successes like Aadhaar and digital access to public services. But there are no short cuts to good quality and adequate healthcare and education services. We must remain optimistic but stay firmly away from the optimism bias.
In the end, it is not about how we start, but how we finish. The disastrous second wave of covid and our inability to manage it is a ghastly reminder of this fact.
On March 31, the World Economic Forum (WEF) released its annual Gender Gap Report 2021. The Global Gender Gap report is an annual report released by the WEF. The gender gap is the difference between women and men as reflected in social, political, intellectual, cultural, or economic attainments or attitudes. The gap between men and women across health, education, politics, and economics widened for the first time since records began in 2006.
[wptelegram-join-channel link=”https://t.me/s/upsctree” text=”Join @upsctree on Telegram”]No need to remember all the data, only pick out few important ones to use in your answers.
The Global gender gap index aims to measure this gap in four key areas : health, education, economics, and politics. It surveys economies to measure gender disparity by collating and analyzing data that fall under four indices : economic participation and opportunity, educational attainment, health and survival, and political empowerment.
The 2021 Global Gender Gap Index benchmarks 156 countries on their progress towards gender parity. The index aims to serve as a compass to track progress on relative gaps between women and men in health, education, economy, and politics.
Although no country has achieved full gender parity, the top two countries (Iceland and Finland) have closed at least 85% of their gap, and the remaining seven countries (Lithuania, Namibia, New Zealand, Norway, Sweden, Rwanda, and Ireland) have closed at least 80% of their gap. Geographically, the global top 10 continues to be dominated by Nordic countries, with —Iceland, Norway, Finland, and Sweden—in the top five.
The top 10 is completed by one country from Asia Pacific (New Zealand 4th), two Sub-Saharan countries (Namibia, 6th and Rwanda, 7th, one country from Eastern Europe (the new entrant to the top 10, Lithuania, 8th), and another two Western European countries (Ireland, 9th, and Switzerland, 10th, another country in the top-10 for the first time).There is a relatively equitable distribution of available income, resources, and opportunities for men and women in these countries. The tremendous gender gaps are identified primarily in the Middle East, Africa, and South Asia.
Here, we can discuss the overall global gender gap scores across the index’s four main components : Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment.
The indicators of the four main components are
(1) Economic Participation and Opportunity:
o Labour force participation rate,
o wage equality for similar work,
o estimated earned income,
o Legislators, senior officials, and managers,
o Professional and technical workers.
(2) Educational Attainment:
o Literacy rate (%)
o Enrollment in primary education (%)
o Enrollment in secondary education (%)
o Enrollment in tertiary education (%).
(3) Health and Survival:
o Sex ratio at birth (%)
o Healthy life expectancy (years).
(4) Political Empowerment:
o Women in Parliament (%)
o Women in Ministerial positions (%)
o Years with a female head of State (last 50 years)
o The share of tenure years.
The objective is to shed light on which factors are driving the overall average decline in the global gender gap score. The analysis results show that this year’s decline is mainly caused by a reversal in performance on the Political Empowerment gap.
Global Trends and Outcomes:
– Globally, this year, i.e., 2021, the average distance completed to gender parity gap is 68% (This means that the remaining gender gap to close stands at 32%) a step back compared to 2020 (-0.6 percentage points). These figures are mainly driven by a decline in the performance of large countries. On its current trajectory, it will now take 135.6 years to close the gender gap worldwide.
– The gender gap in Political Empowerment remains the largest of the four gaps tracked, with only 22% closed to date, having further widened since the 2020 edition of the report by 2.4 percentage points. Across the 156 countries covered by the index, women represent only 26.1% of some 35,500 Parliament seats and 22.6% of over 3,400 Ministers worldwide. In 81 countries, there has never been a woman head of State as of January 15, 2021. At the current rate of progress, the World Economic Forum estimates that it will take 145.5 years to attain gender parity in politics.
– The gender gap in Economic Participation and Opportunity remains the second-largest of the four key gaps tracked by the index. According to this year’s index results, 58% of this gap has been closed so far. The gap has seen marginal improvement since the 2020 edition of the report, and as a result, we estimate that it will take another 267.6 years to close.
– Gender gaps in Educational Attainment and Health and Survival are nearly closed. In Educational Attainment, 95% of this gender gap has been closed globally, with 37 countries already attaining gender parity. However, the ‘last mile’ of progress is proceeding slowly. The index estimates that it will take another 14.2 years to close this gap on its current trajectory completely.
In Health and Survival, 96% of this gender gap has been closed, registering a marginal decline since last year (not due to COVID-19), and the time to close this gap remains undefined. For both education and health, while progress is higher than economy and politics in the global data, there are important future implications of disruptions due to the pandemic and continued variations in quality across income, geography, race, and ethnicity.
India-Specific Findings:
India had slipped 28 spots to rank 140 out of the 156 countries covered. The pandemic causing a disproportionate impact on women jeopardizes rolling back the little progress made in the last decades-forcing more women to drop off the workforce and leaving them vulnerable to domestic violence.
India’s poor performance on the Global Gender Gap report card hints at a serious wake-up call and learning lessons from the Nordic region for the Government and policy makers.
Within the 156 countries covered, women hold only 26 percent of Parliamentary seats and 22 percent of Ministerial positions. India, in some ways, reflects this widening gap, where the number of Ministers declined from 23.1 percent in 2019 to 9.1 percent in 2021. The number of women in Parliament stands low at 14.4 percent. In India, the gender gap has widened to 62.5 %, down from 66.8% the previous year.
It is mainly due to women’s inadequate representation in politics, technical and leadership roles, a decrease in women’s labor force participation rate, poor healthcare, lagging female to male literacy ratio, and income inequality.
The gap is the widest on the political empowerment dimension, with economic participation and opportunity being next in line. However, the gap on educational attainment and health and survival has been practically bridged.
India is the third-worst performer among South Asian countries, with Pakistan and Afghanistan trailing and Bangladesh being at the top. The report states that the country fared the worst in political empowerment, regressing from 23.9% to 9.1%.
Its ranking on the health and survival dimension is among the five worst performers. The economic participation and opportunity gap saw a decline of 3% compared to 2020, while India’s educational attainment front is in the 114th position.
India has deteriorated to 51st place from 18th place in 2020 on political empowerment. Still, it has slipped to 155th position from 150th position in 2020 on health and survival, 151st place in economic participation and opportunity from 149th place, and 114th place for educational attainment from 112th.
In 2020 reports, among the 153 countries studied, India is the only country where the economic gender gap of 64.6% is larger than the political gender gap of 58.9%. In 2021 report, among the 156 countries, the economic gender gap of India is 67.4%, 3.8% gender gap in education, 6.3% gap in health and survival, and 72.4% gender gap in political empowerment. In health and survival, the gender gap of the sex ratio at birth is above 9.1%, and healthy life expectancy is almost the same.
Discrimination against women has also been reflected in Health and Survival subindex statistics. With 93.7% of this gap closed to date, India ranks among the bottom five countries in this subindex. The wide sex ratio at birth gaps is due to the high incidence of gender-based sex-selective practices. Besides, more than one in four women has faced intimate violence in her lifetime.The gender gap in the literacy rate is above 20.1%.
Yet, gender gaps persist in literacy : one-third of women are illiterate (34.2%) than 17.6% of men. In political empowerment, globally, women in Parliament is at 128th position and gender gap of 83.2%, and 90% gap in a Ministerial position. The gap in wages equality for similar work is above 51.8%. On health and survival, four large countries Pakistan, India, Vietnam, and China, fare poorly, with millions of women there not getting the same access to health as men.
The pandemic has only slowed down in its tracks the progress India was making towards achieving gender parity. The country urgently needs to focus on “health and survival,” which points towards a skewed sex ratio because of the high incidence of gender-based sex-selective practices and women’s economic participation. Women’s labour force participation rate and the share of women in technical roles declined in 2020, reducing the estimated earned income of women, one-fifth of men.
Learning from the Nordic region, noteworthy participation of women in politics, institutions, and public life is the catalyst for transformational change. Women need to be equal participants in the labour force to pioneer the societal changes the world needs in this integral period of transition.
Every effort must be directed towards achieving gender parallelism by facilitating women in leadership and decision-making positions. Social protection programmes should be gender-responsive and account for the differential needs of women and girls. Research and scientific literature also provide unequivocal evidence that countries led by women are dealing with the pandemic more effectively than many others.
Gendered inequality, thereby, is a global concern. India should focus on targeted policies and earmarked public and private investments in care and equalized access. Women are not ready to wait for another century for equality. It’s time India accelerates its efforts and fight for an inclusive, equal, global recovery.
India will not fully develop unless both women and men are equally supported to reach their full potential. There are risks, violations, and vulnerabilities women face just because they are women. Most of these risks are directly linked to women’s economic, political, social, and cultural disadvantages in their daily lives. It becomes acute during crises and disasters.
With the prevalence of gender discrimination, and social norms and practices, women become exposed to the possibility of child marriage, teenage pregnancy, child domestic work, poor education and health, sexual abuse, exploitation, and violence. Many of these manifestations will not change unless women are valued more.
[wptelegram-join-channel link=”https://t.me/s/upsctree” text=”Join @upsctree on Telegram”]2021 WEF Global Gender Gap report, which confirmed its 2016 finding of a decline in worldwide progress towards gender parity.
Over 2.8 billion women are legally restricted from having the same choice of jobs as men. As many as 104 countries still have laws preventing women from working in specific jobs, 59 countries have no laws on sexual harassment in the workplace, and it is astonishing that a handful of countries still allow husbands to legally stop their wives from working.
Globally, women’s participation in the labour force is estimated at 63% (as against 94% of men who participate), but India’s is at a dismal 25% or so currently. Most women are in informal and vulnerable employment—domestic help, agriculture, etc—and are always paid less than men.
Recent reports from Assam suggest that women workers in plantations are paid much less than men and never promoted to supervisory roles. The gender wage gap is about 24% globally, and women have lost far more jobs than men during lockdowns.
The problem of gender disparity is compounded by hurdles put up by governments, society and businesses: unequal access to social security schemes, banking services, education, digital services and so on, even as a glass ceiling has kept leadership roles out of women’s reach.
Yes, many governments and businesses had been working on parity before the pandemic struck. But the global gender gap, defined by differences reflected in the social, political, intellectual, cultural and economic attainments or attitudes of men and women, will not narrow in the near future without all major stakeholders working together on a clear agenda—that of economic growth by inclusion.
The WEF report estimates 135 years to close the gap at our current rate of progress based on four pillars: educational attainment, health, economic participation and political empowerment.
India has slipped from rank 112 to 140 in a single year, confirming how hard women were hit by the pandemic. Pakistan and Afghanistan are the only two Asian countries that fared worse.
Here are a few things we must do:
One, frame policies for equal-opportunity employment. Use technology and artificial intelligence to eliminate biases of gender, caste, etc, and select candidates at all levels on merit. Numerous surveys indicate that women in general have a better chance of landing jobs if their gender is not known to recruiters.
Two, foster a culture of gender sensitivity. Take a review of current policies and move from gender-neutral to gender-sensitive. Encourage and insist on diversity and inclusion at all levels, and promote more women internally to leadership roles. Demolish silos to let women grab potential opportunities in hitherto male-dominant roles. Work-from-home has taught us how efficiently women can manage flex-timings and productivity.
Three, deploy corporate social responsibility (CSR) funds for the education and skilling of women and girls at the bottom of the pyramid. CSR allocations to toilet building, the PM-Cares fund and firms’ own trusts could be re-channelled for this.
Four, get more women into research and development (R&D) roles. A study of over 4,000 companies found that more women in R&D jobs resulted in radical innovation. It appears women score far higher than men in championing change. If you seek growth from affordable products and services for low-income groups, women often have the best ideas.
Five, break barriers to allow progress. Cultural and structural issues must be fixed. Unconscious biases and discrimination are rampant even in highly-esteemed organizations. Establish fair and transparent human resource policies.
Six, get involved in local communities to engage them. As Michael Porter said, it is not possible for businesses to sustain long-term shareholder value without ensuring the welfare of the communities they exist in. It is in the best interest of enterprises to engage with local communities to understand and work towards lowering cultural and other barriers in society. It will also help connect with potential customers, employees and special interest groups driving the gender-equity agenda and achieve better diversity.
