=========================

The linear attenuation coefficient (LAC) determines the proportion of X-rays that are removed from the beam per unit distance. We will review the function of a coefficient and how that should help us to conceptualise LAC. LAC is determined by the combination of the photoelectric effect, compton scatter and rayleigh scatter - therefore, the X-ray beam energy, density of the tissue and atomic number of the tissue all contribute to the LAC.

Not sure these radiology physics question banks are for you?

If you’re preparing for a radiology physics exam and feeling overwhelmed by formulas, theory, or endless reading, you’re not alone. Most candidates don’t fail because they didn’t study enough, but because they didn’t practise the right way.

The fastest way to build confidence in radiology physics is simple:
👉 Do high-quality past-paper style questions.

Instead of passively reading notes, you’ll practise the way the exams actually test you. With carefully written questions that reflect real exam structure, difficulty, and marking logic.

Why question banks work for radiology physics exams

Radiology physics isn’t about memorising every fact. It’s about recognising patterns, understanding how concepts are tested, and applying physics under exam pressure. These question banks help you:

Identify high-yield examinable topics
Learn how questions are phrased across different exams and modalities
Recognise common exam traps and misconceptions
Reinforce understanding through repetition and explanation
Build the confidence that comes from knowing you’ve seen this before

Every question is written with exam relevance in mind, aligned to major international curricula, and structured to mirror real-world past papers, not generic AI generated physics quizzes.

Who these radiology physics question banks are for

These are ideal if you:

Are short on time and want maximum exam return
Feel confident reading theory but struggle with exam questions
Want a structured way to revise X-ray, CT, MRI, ultrasound, and nuclear medicine physics

Are preparing for FRCR, RANZCR AIT, ARRT, ABR Core, MICR Part 1, or FC Rad Diag (SA) or similar exams in the Radiography and Veterinary fields.

If you’ve ever thought “I understand this topic… but I’m not sure I could answer it in an exam”, this is exactly the gap these question banks are built to close.

Radiology physics exams reward practice, familiarity, and confidence.
And confidence comes from doing focused, exam specific practice over and over again.

Happy studying,
Michael
