Radiation Protection & Health Physics for RSO-MRF

Radiation protection and health physics form the practical heart of an RSO's job — this is the material that turns physics knowledge into everyday hazard control. Here's how it's structured for the RSO-MRF exam.

RSO-MRF Syllabus · Topics 11 & 12 Frequently tested in viva-voce

Radiation Protection Standards

This covers how radiation dose limits are set, and by whom:

Radiation dose to individuals from natural background radiation and man-made sources
Basic concepts underlying radiation protection standards, and the role of the International Commission on Radiological Protection (ICRP)
Categories of exposure and associated risk factors
International and national standards — ICRP, the Basic Safety Standards (BSS), and AERB's own regulatory limits
UNSCEAR recommendations and how they inform national policy
Dose limits for occupational workers, the general public, comforters, and trainees

Radiation Hazard Evaluation and Control

This is where health physics becomes applied engineering — the practical calculations an RSO does to design and verify a safe facility:

Internal versus external radiation hazards, and how each is evaluated and controlled
Individual and workplace monitoring practices
Applying time, distance, and shielding — the three fundamental tools of radiation protection
Shielding calculation parameters: workload (W), use factor (U), occupancy factor (T)
Primary and secondary protective barrier design
Shielding requirements specific to diagnostic X-ray facilities, telecobalt units, medical accelerators, brachytherapy installations, and radioisotope laboratories
Calibration and use of radiation monitoring instruments
Protective measures to reduce exposure to both patients and occupational workers

Why this matters beyond the exam

Health physics and radiation protection aren't just exam topics — they're the day-to-day substance of the RSO role. Viva-voce examiners frequently probe scenario-based questions here: "how would you evaluate a shielding requirement for a new telecobalt room," or "what's your monitoring protocol if a survey meter shows an unexpected reading." Strong conceptual grounding here pays off well beyond passing the exam.
