What is the common examiner trap about Science & Tech in UPSC exams?

They may ask which body upheld the LNT model in 2021 (U.S. NRC) versus which body eliminated ALARA in 2026 (U.S. DOE), creating confusion between different U.S. agencies. They may also swap the concepts of 'ALARA' and 'LNT' or present 'hormesis' as the currently accepted regulatory model.

What should UPSC aspirants remember about Science & Tech for Prelims?

1. Target this Data: U.S. DOE eliminated ALARA on January 12, 2026. 2. Target this Nodal Body: International Commission on Radiological Protection (ICRP) and U.S. Department of Energy (DOE). 3. Target this Legal Point: The foundational principles are the LNT Model and the ALARA philosophy.

U.S. DOE Eliminates ALARA Philosophy, Diverges from Global Radiation Protection Framework

Q: The International Commission on Radiological Protection (ICRP) is primarily responsible for providing recommendations on which of the following areas?

Radiation protection and safety standards, The ICRP is an independent international body that provides recommendations and guidance on all aspects of protection against ionizing radiation. Its recommendations form the scientific basis for radiation safety standards globally, including those of the IAEA.

Q: Consider the following statements regarding the news on radiation safety: 1. The U.S. Department of Energy (DOE) eliminated the ALARA principle from its directives in January 2026. 2. The Linear No-Threshold (LNT) model suggests there is a safe threshold dose below which radiation exposure is completely risk-free. 3. The International Atomic Energy Agency (IAEA) bases its Basic Safety Standards on the recommendations of the ICRP. Which of the statements given above is/are correct?

Both 1 and 3, Statement 1 is correct as per the article: the U.S. DOE eliminated ALARA on January 12, 2026. Statement 2 is incorrect; the core of the LNT model is that there is NO safe threshold, and risk increases linearly with dose. Statement 3 is correct; the IAEA updates its Basic Safety Standards using inputs from the ICRP.

Q: According to the news article, on which date did the U.S. Department of Energy eliminate the ALARA philosophy from its directives?

January 12, 2026, The article explicitly states that on January 12, the U.S. Department of Energy (DOE) 'eliminated' ALARA from its directives and regulations. February 18, 2026, is the article's publication date. November 9, 2023, is the date of a cited Nature Medicine study.

Q: What is a major criticism, as mentioned in the article, of the U.S. DOE's decision to eliminate the ALARA principle?

It appears politically motivated and risks undermining worker protection and public trust., Critics in the article argue that the shift appears politically motivated, relies on non-peer-reviewed internal reports, and risks undermining worker protection, public trust, and regulatory coherence. The other options are contrary to the article's content.

What This Article Covers

1.The U.S. Department of Energy (DOE) eliminated the ALARA (As Low As Reasonably Achievable) principle from its directives on January 12, 2026.

2.This move diverges from the long-standing international radiation protection framework based on the Linear No-Threshold (LNT) model and is criticized for lacking peer-reviewed scientific backing.

3.The shift creates friction with global bodies like the ICRP and IAEA, which are updating their safety standards, and could impact public perception and the social license for nuclear projects.

The Big Picture

Prelims · HighMains · High

The U.S. Department of Energy has unilaterally removed the foundational ALARA radiation safety principle, challenging the decades-old global consensus led by the International Commission on Radiological Protection (ICRP). This policy shift, seen as politically motivated, risks undermining worker protection, public trust, and international regulatory coherence while global bodies are still in the process of modernizing their recommendations.

News Snapshot

⚠️

Policy Shift

The U.S. DOE has unilaterally eliminated the ALARA principle, a cornerstone of global radiological safety for decades.

🌍

International Discord

This move puts the U.S. at odds with international bodies like the ICRP, UNSCEAR, WHO, and its own NRC, which uphold the LNT model.

🔬

Scientific Debate

No large-scale evidence supports replacing the LNT model with alternatives like hormesis, which lacks reproducible human data for regulatory use.

Detailed Analysis & Strategic Depth

Context / Background

The Linear No-Threshold (LNT) model and the ALARA principle have formed the bedrock of the global radiation protection framework for decades. The LNT model posits that any amount of ionizing radiation carries a cancer risk, with no safe threshold. ALARA is the operational philosophy that aims to minimize exposure as low as reasonably achievable, balancing safety with feasibility and cost. This framework is maintained by the International Commission on Radiological Protection (ICRP) and adopted worldwide.

Core Analysis & Implications

The U.S. DOE's elimination of ALARA is a significant departure from international norms, reportedly to foster nuclear innovation. Critics argue it is politically motivated, relies on non-peer-reviewed reports, and risks worker safety and public trust. It creates regulatory incoherence as the ICRP and IAEA are in the process of modernizing their 2007 recommendations and 2014 Basic Safety Standards, respectively. The policy shift could deepen public mistrust, fuel opposition to nuclear projects, and complicate securing a 'social license' for facilities.

Future Outlook / Way Forward

The ICRP continues its comprehensive revision with over 25 task groups, though no target year is set. The IAEA will update its standards based on ICRP inputs. The debate hinges on scientific consensus; recent studies like the 'Million Person Study' suggest possible low-dose effects, which the ICRP must consider. Effective public communication and transparent engagement are critical to prevent policy shifts from being perceived as a lowering of safety standards rather than scientific refinement.

India's Position

The article notes that India has been at the forefront of complying with internationally accepted radiation protection practices, as stated by a former secretary of the Atomic Energy Regulatory Board (AERB). India is expected to continue aligning with global standards set by bodies like the ICRP and IAEA, rather than following the U.S.'s unilateral move.
