Medical Applications — Prelims Strategy

Prelims Strategy

To master 'Medical Applications of Nuclear Technology' for Prelims, aspirants should adopt a multi-faceted approach focusing on factual accuracy and conceptual clarity. Firstly, create a comprehensive table of key radioisotopes (e.

g., Tc-99m, F-18, I-131, Co-60, Lu-177), noting their half-life (general idea), type of radiation emitted, and specific diagnostic or therapeutic applications. Understand the basic working principles of PET and SPECT scans, focusing on what they image (function vs.

structure) and their primary uses. Memorize the roles of BARC (R&D, production), BRIT (supply, marketing), and AERB (regulation) as institutional pillars. Pay close attention to current affairs related to new medical isotope discoveries, indigenous production initiatives (e.

g., new cyclotrons), and advancements like theranostics, noting their significance. Practice MCQs that test direct recall, matching pairs, and conceptual understanding of safety principles like ALARA.

Focus on keywords and their definitions, ensuring you can differentiate between similar-sounding terms. Regularly revise these facts using mnemonics and quick revision notes to ensure retention.
