Try 3 questions from the Radiation Protection guide

This is the style of every question in our guides: exam-like, original, and explained.

1. The dose rate at 3 m from a source is 4 mGy/h. What is the dose rate at 1 m?

  1. 1.3 mGy/h
  2. 12 mGy/h
  3. 36 mGy/h
  4. 108 mGy/h
Show answer

C – 36 mGy/h. Inverse square law: moving from 3 m to 1 m multiplies the dose rate by (3/1)² = 9, so 4 × 9 = 36 mGy/h.

2. A radiographer wears a lead apron and a single personal dosimeter during fluoroscopy. Where should the dosimeter be worn?

  1. At waist level under the apron
  2. In the pocket of the scrubs
  3. On the wrist
  4. At collar level outside the apron
Show answer

D. At collar level outside the apron it estimates the dose to the unshielded thyroid and eyes.

3. Dose limits do NOT apply to:

  1. Radiographers
  2. Members of the public in the waiting room
  3. Patients undergoing medical examinations
  4. Radiography students aged 17
Show answer

C. Medical exposure of patients is controlled by justification and optimisation, not by dose limits. A classic exam trap.

Are these real exam questions?

Which exam is this for?

The SCFHS Radiography Technician classification exam and the Saudi Radiologic Technologist Licensure Examination (SRTLE). The content is also relevant for radiographer licensing exams in the UAE (DHA, DOH) and Qatar (QCHP).

Why is the guide in English?

Because the exam is in English. Practising with the same terminology you will see on exam day is the best preparation.
