Background Radiation high in Kerala: Study

Central idea: The article discusses a pan-India study conducted by scientists at the Bhabha Atomic Research Centre (BARC) which found that background radiation levels in parts of Kerala are nearly three times more than what’s been assumed.

What is Background Radiation?

Background radiation is a measure of the level of ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources.
Background radiation originates from a variety of sources, both natural and artificial.

Nuclear Radiation and its Types

There are three main types of nuclear radiation: alpha particles, beta particles, and gamma rays.

1. Alpha particles are made up of two protons and two neutrons and are essentially helium nuclei. They have a positive charge and are relatively large and heavy, which means they can be stopped by a piece of paper or the outer layer of skin.

2. Beta particles are high-energy electrons that are emitted from the nucleus of an atom. They have a negative charge and are much smaller than alpha particles, which means they can penetrate through the skin and into the body.

3. Gamma rays are high-energy electromagnetic radiation, similar to X-rays. They are emitted from the nucleus of an atom and have no charge. They are extremely penetrating and can travel long distances through air and most materials, including the human body.

How is it measured?

The International Atomic Energy Agency (IAEA) specifies maximum radiation exposure levels and this has also been adopted by India’s atomic energy establishment.
Public exposure shouldn’t exceed 1 milli-Sievert every year, those who work in plants or are by virtue of their occupation shouldn’t be exposed to over 30 milli-Sievert every year.
Generally it is measured in nanogray per second. A (nGy/s) is a decimal fraction of the SI-derived unit of ionizing radiation absorbed dose rate.

Natural sources-

Cosmic radiation
Environmental radioactivity from naturally occurring radioactive materials (such as radon and radium)

Man-made sources-

Medical X-rays,
Fallout from nuclear weapons testing and nuclear accidents.

Factors affecting such radiation

Natural background radiation is all around us.
Background radiation varies from place to place and over time, depending on the amount of naturally occurring radioactive elements in soil, water and air.
Weather conditions also affect radiation levels, as snow cover may shield these elements, and radioactive particulates can wash out of the air during rain storms.
Cosmic radiation from the sun, our galaxy, and beyond is constantly around us and contributes to natural background radiation.
Altitude and latitude can also influence the level of background radiation at any one site.

How threatening is it?

All rocks and soils contain some trace amount of natural radioactivity and can sometimes be ingested or inhaled if disturbed.
Radon is a gas that can concentrate indoors and be inhaled, along with its decay products.
We can also ingest radioactivity from the food we eat and the water we drink.
A number of factors determine the annual dose you and your family receive from background radiation.
Typically, Gamma rays are a type of such radiation that can pass through matter unobstructed, and are harmless in small doses, but can be dangerous in concentrated bursts.

Findings of the BARC Study

The study found that the average natural background levels of gamma radiation in India was 94 nGy/hr (nano Gray per hour) (or roughly 0.8 millisievert/year).
The last study conducted in 1986 computed such radiation to be 89 nGy/hr.
The study found that the levels in Kollam district, Kerala were 9,562 nGy/hr, or about three times more than what was assumed.
This computes to about 70 milliGray a year, or a little more than what a worker in a nuclear plant is exposed to.
This however does not necessarily mean that those at Kollam are being exposed to dangerous levels of radiation, as past studies have not found any higher rates of cancer or mortality.

Reasons for Higher Radiation Levels in Kerala

The higher radiation levels in Kollam are attributed to monazite sands that are high in thorium, which is part of India’s long-term plan to sustainably produce nuclear fuel.
Southern India has higher levels of radiation due to the presence of granite and basaltic, volcanic rock, which contains uranium deposits.

How India’s Sugar Exports to the world are surging?
Central idea: India’s success story in sugar exports
- India’s sugar exports have soared from $810.9 million in 2017-18 to $4.6 billion in 2021-22, and could cross $5.5 billion in the fiscal year ending March 31.
- The increase is significant in quantity terms too, with India’s shipments increasing from a mere 0.46 lakh tonnes in 2016-17 to 110 lakh tonnes in 2021-22.
- India has gone from being a marginal player in sugar exports five years ago to No. 2 in the world currently, behind only Brazil.
Favourite destinations
- The biggest importers of Indian raw sugar were Indonesia (16.73 lt), Bangladesh (12.10 lt), Saudi Arabia (6.83 lt), Iraq (4.78 lt) and Malaysia (4.15 lt).
- The country also exported 53.71 lt of white/ refined sugar, the leading destinations for which included Afghanistan (7.54 lt), Somalia (5.17 lt), Djibouti (4.90 lt), Sri Lanka (4.27 lt), China (2.58 lt), and Sudan (1.08 lt).
- The highest decline in exports has been registered by the European Union (which produces sugar from beet, unlike India and Brazil that only crush cane): from 39.74 lt in 2017-18 to 8.02 lt in 2021-22.
Which grades of sugar does India export?
- Raw sugar is what mills produce after the first crystallization of juice obtained from crushing of cane.
- This sugar is rough and brownish in color, with an ICUMSA value of 600-1,200 or higher.
- ICUMSA is a measure of the purity of sugar based on color.
- This raw sugar is processed in refineries for removal of impurities and de-colorization.
- The end product is refined white cane sugar having a standard ICUMSA value of 45.
- Till 2017-18, India mainly shipped plantation white sugar with 100-150 ICUMSA value, also known as low-quality whites or LQW in international markets.
Reasons behind India’s surge in sugar exports
- Indian raw sugar is free of dextran, unlike Brazilian raws.
- Indian mills can supply raws with a very high polarization of 98.5-99.5%, which is higher than the polarization of raws from Brazil, Thailand, and Australia.
- Indian raws today fetch a 4% premium over the global benchmark (New York No. 11 futures contract) price, while LQW sells at a $40/tonne discount to the world price (London No. 5 futures) for 45 ICUMSA whites.
- Indonesia agreed to tweak its norms in December 2019 to enable imports from India, which further boosted India’s efforts to push exports of raws.

Operation Greens Scheme: TOP Farmers Protests And A Way Ahead
Central Idea
- The Operation Greens scheme aimed to develop a value chain for reducing extreme price fluctuations in the three basic vegetables (tomatoes, onions, and potatoes), enhance farmers’ realizations, and improve their share of the consumer rupee. However, the scheme has not been successful in achieving its goals, as seen by the recent protests against low prices by onion and potato farmers.
What is Operation Greens scheme?
- The Operation Greens scheme is a government initiative launched in the 2018-19 Union budget by the present government.
- It aims to develop a value chain for reducing extreme price fluctuations in the three basic vegetables, including tomatoes, onions, and potatoes (TOP).
- The scheme was later expanded to 22 perishable crops in the 2021-22 budget.
- The government hopes that by developing a sustainable value chain for these perishable commodities, farmers will benefit from better price realization, while consumers will have access to quality products at reasonable prices.
Aim & Objectives:
- To enhance value realization of TOP farmers; reduction in post-harvest losses; price stabilization for producer and consumers and increase in food processing capacities and value addition.
- Price stabilisation for producers and consumers by proper production planning in the TOP clusters and introduction of dual-use varieties.
- Reducing post-harvest losses by creation of farm gate infrastructure, development of suitable agro-logistics, creation of appropriate storage capacity linking consumption centres.
- Increasing food processing capacities and value addition in the TOP value chain with firm linkages with production clusters.
- Setting up a market intelligence network to collect and collate real-time data on demand and supply and price of TOP crops.
Components:
- Short-term intervention by way of providing transportation and storage subsidy @ 50% and
- long-term intervention through value addition projects in identified production clusters with Grant-in-aid @ 35% to 70% of the eligible project cost subject to a maximum of Rs. 50 crore per project
Limited Success of Operation Greens Scheme
- Retail tomato prices: Tomato prices in wholesale markets have dropped significantly, but retail prices have not reduced much, indicating limited success.
- Low Onion price: Onion and potato farmers are protesting against low prices, highlighting the scheme’s lack of effectiveness.
- For instance: There are protests by Maharashtra’s onion growers against low prices, including relay hunger fasts, stoppage of auctions at major mandis, and a 200-km march to Mumbai. Similarly, potato farmers in Uttar Pradesh have demanded that the government procure their tuber at Rs 10 per kg, as against the ruling Rs 6-6.5/kg market price at Agra.
Reasons behind its limited success
- Problem Not with Lack of Storage or Processing Capacity: UP alone has an abundance of cold stores with ample capacity to store perishable goods like potatoes. Maharashtra’s growers have built enough kandha chawls to store onions for 4-6 months. Despite the creation of storage capacity, price volatility persists in milk and cane payment arrears to farmers.
- Price Volatility: The prices of TOP crops have been volatile, which has adversely affected both farmers and consumers. The prices of these commodities tend to fluctuate sharply due to seasonality, weather conditions, and other factors, resulting in uncertainty and instability in the market.
- Implementation Issues: The scheme’s implementation has been marred by delays, bureaucratic hurdles, and lack of coordination among various stakeholders, which has resulted in low participation and limited success.
- Lack of Market Linkages: Another reason for limited success is the lack of market linkages between producers and consumers. The farmers are unable to access markets directly, which leads to dependence on intermediaries who manipulate prices, resulting in price volatility.
Need for Price or Income Assurance for Farmers
- Investment: Investment in farm-gate, agri-logistics, and storage-cum-processing infrastructure needs to be encouraged.
- Assurance: Price or income assurance for farmers is necessary, especially for horticulture, dairy, and poultry producers who do not enjoy minimum support price benefits.
- Diversification: The future for Indian agriculture lies in crop diversification, which will spur greater consumption of foods incorporating proteins (pulses, milk, eggs, and meat) and micro-nutrients (fruits and vegetables), instead of only calories and carbohydrates.
- Deficiency price payments: The deficiency price payments or per-hectare direct income transfers could be the way forward.
Conclusion
- It is evident that the limited success of the Operation Greens scheme underscores the urgent need for a more comprehensive approach to address the challenges faced by TOP farmers. A more holistic approach is required that prioritizes farmer empowerment, investment in infrastructure, and promotion of crop diversification. By adopting such an approach, the government can not only mitigate the impact of price volatility on farmers but also achieve its broader goal of building a sustainable and resilient agricultural sector that benefits both producers and consumers alike.
Mains Question

Q. What is Operation Greens scheme? Analyse its limited success in achieving its objectives and Suggest measures to improve the scheme’s effectiveness.

National Champions Model for Infrastructure Development: Pros and Cons
Central Idea
- Emerging economies struggle to provide functional and efficient infrastructure. Infrastructure has become a national aspiration good, a mechanism for job creation, and a necessity. The two biggest constraints on infrastructure provision are cost and public good component. This national champion’s model aims to incentivize private sector participation in infrastructure investments, but it also has its own set of challenges and limitations.
Traditional Financing Approaches and their Limitations
- The traditional approach to financing infrastructure has relied on tax revenues or government borrowing.
- However, this creates a vicious trap as poorer economies generate less tax revenue, which limits infrastructure investment, leading to a further spinoff that affects the growth of the economy and keeps the country poor.
- Increasing public borrowing domestically tends to crowd out private investment, exacerbating the problem.
The Public-Private Partnership Model and its Problems
- The Indian government tried to incentivize private sector participation in infrastructure investment by introducing the Public-Private-Partnership (PPP) model in the early 2000s.
- While the PPP model led to the construction of a lot of infrastructure, it ended in an avalanche of non-performing assets with public sector banks, private sector bankruptcies, accusations of widespread corruption, and a change in government in 2014.
The National Champions Model and its Innovations
- The present government has modified the PPP approach by assigning the bulk of infrastructure provisioning for roads, ports, airports, energy, and communications to a few chosen industrial houses.
- This is the national champions model where the government picks a few large conglomerates to implement its development priorities.
- This model incentivizes national champions to build projects by providing subsidies to cover the costs.
- New aspects of the National Champions Model:
1. National champions need control over existing projects with strong cash flows to incentivize investment in projects with low returns and negative cash flows.
2. Public association of champions with the government’s national development policy generates a competitive advantage for the champions in getting domestic and foreign contracts.
3. Access to some cash-rich projects allows national champions to borrow from external credit markets by using these entities as collateral, which lowers the cost of finance of other.
Benefits of National Champions Model
- Economic growth: National champions can contribute to economic growth by generating revenue, creating jobs, and investing in research and development.
- Strategic importance: The model can help ensure that the country has a strong presence in strategically important industries, such as defense or energy, which can be critical to national security.
- Export competitiveness: National champions can become leaders in their respective markets and compete effectively in global markets, which can increase exports and improve the country’s trade balance.
- Innovation: National champions can invest heavily in research and development, leading to technological advancements that can benefit the broader economy.
- Access to capital: National champions may be able to access capital more easily than smaller companies, allowing them to make larger investments and pursue growth opportunities.
The Problems with the National Champions Model
- Too big to fail: Market and regulatory treatment of conglomerates as too big to fail. This means that these companies are so large and important to the economy that their failure could cause widespread harm to the financial system and the economy as a whole. This opens the door to market hysteria, delayed discovery of problems, and spillovers of sectoral problems into systemic shocks. The recent troubles of the Adani companies in India highlight the potential risks associated with this approach.
- Encouraging market concentration that can be bad for efficiency and productivity: Concentrated markets reduce competition and can lead to higher prices, lower quality, and reduced innovation. When firms have market power, they have less incentive to improve their products or services, reduce costs, or innovate. This can result in lower overall productivity in the economy.
- The risk of turning the country into an industrial oligarchy: An industrial oligarchy is where a small group of powerful and influential conglomerates control a large portion of the economy. This can have negative consequences for economic growth, social mobility, and political stability. An oligarchy may be resistant to change and less responsive to the needs and aspirations of the broader population.
- Uneven playing field: The optics of an uneven playing field in terms of market access and selective regulatory forbearance that can become a significant deterrent for foreign investors.
Conclusion
- While infrastructure is a necessary condition for growth, it is not a sufficient one. Effective demand is the problem, as seen in the power sector, where the inability of the power distribution companies to recover payments was the issue. India is at an inflection point in its development path, and the national champions model has its pros and cons that needs to be analyzed before its consideration.

Paramilitary Forces: Addressing Concerns and Demands
Central Idea
- Last month, India observed the day of remembrance for the Pulwama attack that took place on February 14, 2019, which resulted in the death of 40 Central Reserve Police Force (CRPF) personnel. The lesson learned is that there is an urgent need to address the grievances of paramilitary forces in terms of training, morale, and parity with regular armed forces to ensure the effectiveness of these forces in maintaining internal security.
Background
- The Forgotten Dantewada Attack: An earlier attack on April 6, 2010, in which 76 CRPF personnel were killed by left-wing extremists in Dantewada, has faded away from public attention despite being the deadliest attack on security forces in any counter-insurgency or anti-terrorist operations in independent India.
- The Pulwama attack: The attack on February 14, 2019, claimed the lives of 40 personnel of the Central Reserve Police Force (CRPF), India’s largest paramilitary force. The Pulwama attack resulted in an unprecedented public outcry and evoked emotional responses across all sections of society. It is important to remember this incident to prevent a repeat in the future.
Central Reserve Police Force (CRPF)
- Motto: “Service and Loyalty”
- Logo: The CRPF logo features a crossed rifle and a light machine gun over a map of India, with a laurel wreath and the words “Central Reserve Police Force” written in both Hindi and English. The crossed rifles and the light machine gun represent the CRPF’s role in maintaining internal security, while the map of India signifies its national duty.
- Establishment: CRPF is the largest Central Armed Police Force of India. It was established in 1939 as the Crown Representative’s Police (CRP) to assist British rulers in managing unrest and law and order issues. After India gained independence in 1947, it became the Central Reserve Police Force.
- Responsibility: The CRPF is primarily responsible for maintaining internal security, counter-terrorism operations, and assisting the state police in maintaining law and order. It also assists in disaster management and protects vital installations.
- Personnel and deployment: With more than 300,000 personnel, the CRPF is one of the most significant components of India’s internal security apparatus. It operates in a variety of environments, including urban, jungle, and mountainous terrain. The CRPF has also been deployed in international peacekeeping operations, such as in Haiti, Sudan, and Congo.
Challenges Faced by Paramilitary Forces
- Security threats: Paramilitary forces are often deployed in areas where there are security threats such as terrorist attacks, insurgencies, and border conflicts. These threats pose a significant risk to the lives of the personnel, and they have to be constantly vigilant to prevent any untoward incidents.
- Pay and benefits: The Indian Army personnel receive higher pay, better benefits, and retirement benefits compared to paramilitary forces. The Indian Army also has a well-established pension system, while paramilitary forces have a Contributory Pension Scheme (CPS).
- Inadequate infrastructure: These forces often operate in remote areas with inadequate infrastructure, including basic facilities such as food, water, and shelter. This makes it challenging for the personnel to carry out their duties effectively, especially during long deployments.
- Inadequate training: Proper training is essential for paramilitary personnel to carry out their duties effectively. However, due to budget constraints and a lack of resources, training is often inadequate, which can lead to inefficiencies and mistakes during operations.
- De-induction of Army: The deinduction of the Indian Army from certain areas has led to the CRPF (Central Reserve Police Force) and other paramilitary forces being tasked with carrying out hard duties, leading to overstretched personnel and compromised training.
- Stress and mental health: The nature of the job is often stressful, and paramilitary personnel are frequently exposed to traumatic situations that can have long-term effects on their mental health. Unfortunately, mental health resources are often limited, and the stigma surrounding mental health issues can prevent personnel from seeking help.
- Lack of modern equipment: Paramilitary forces require modern equipment and weapons to carry out their duties effectively. However, due to budget constraints and bureaucratic red tape, acquiring such equipment is often delayed, which puts the personnel at risk.
Need for Parity and Better Treatment
- Armed Forces of the union category: The Delhi High Court order of December 2022 that recognised the paramilitary as a force under the category of ‘Armed Forces of the union’ and underscores the need to address the genuine grievances of the paramilitary personnel.
- Service facilities: The paramilitary force faces discrimination in matters ranging from pension to service facilities.
- Old pension scheme: Former personnel and their families have demanded the old pension scheme for serving members of the paramilitary force.
- Training: The training and morale of paramilitary personnel must be taken care of to maintain optimum performance and effectiveness.
Other key paramilitary and special forces in India
- National Security Guard (NSG): NSG is a federal contingency force tasked with counter-terrorism and special operations. It was established in 1984 and operates under the Ministry of Home Affairs.
- Border Security Force (BSF): BSF is a border guarding force responsible for guarding India’s land borders during peace time and preventing trans-border crimes. It was established in 1965 and operates under the Ministry of Home Affairs.
- Sashastra Seema Bal (SSB): SSB is a border guarding force tasked with guarding India’s borders with Nepal and Bhutan. It was established in 1963 and operates under the Ministry of Home Affairs.
- Indo-Tibetan Border Police (ITBP): ITBP is a specialized mountain force responsible for guarding India’s borders with China. It was established in 1962 and operates under the Ministry of Home Affairs.
- Assam Rifles: Assam Rifles is a paramilitary force responsible for maintaining law and order in the northeast region of India. It was established in 1835 and operates under the Ministry of Home Affairs.
Conclusion
- The observance of Pulwama day should serve as a reminder to avoid a repeat of the tragedy and calls for analysing the lessons learnt and taking corrective measures. It is important to listen to the genuine grievances of the paramilitary personnel to maintain their morale and enhance the security environment of the nation.

Women Leadership: Conditions To Unleash Her Potential
Central Idea
- Today the world is home to a transformative generation of 900 million adolescent girls and young women poised to shape the future of work and growth. If this cohort of young women could be equipped with the right resources and opportunities to nurture the 21st century skills, they would become the largest segment of women leaders, change-makers, entrepreneurs, and innovators in history.
Women In India
- India is home to one of the largest generations of girls and young women, has made significant progress across various domains, such as education, health, digital and financial inclusion, and leadership building, to achieve Sustainable Development Goal 5, which envisions a more gender-equal world by 2030.
- To unleash the gender dividend and create conditions for female leadership to flourish, women at all levels of society must have inclusion in the Information and Communications Technology (ICT), bodily autonomy and safety, shared responsibility within the household, and equal participation in decision-making spaces.
What are the necessary conditions that must be in place for Women leadership to thrive?
1. Cultivating Agency:
- Given the socio-economic barriers that adolescent girls confront from their earliest years that the work to cultivate their agency must begin early.
- India’s initiatives across various domains, such as education, health, digital and financial inclusion, and leadership building, to achieve Sustainable Development Goal 5, which envisions a more gender-equal world by 2030.
1. Inclusion in ICT:
- Inclusion in Information and Communications Technology (ICT) for women at all levels of society is very important.
- As access to digital technology increasingly becomes an arena of opportunity and basic service, EdTech can bridge the accessibility gap in education through hybrid learning models, even where girls’ access to schooling is restricted by harmful norms.
1. STEM Education:
- The prevailing stereotypes that characterize STEM education as a traditionally masculine domain, even though over 43% of Indian STEM graduates are women.
- The gender norms that disproportionately allocate domestic and care responsibilities to women, representation of men as leaders of STEM, finance, and entrepreneurial fields in the public perception, and institutional mechanisms are some of the barriers that explain why increased women’s representation in STEM education does not translate into work participation.
