How to prepare

How to prepare for your Radiology Technician interview

Master radiation safety fundamentals — ALARA, time-distance-shielding, lead protection and personal dosimetry — as these are always tested.

Revise positioning for common projections (chest, abdomen, extremities, spine) and the exposure factors that affect each.

Understand the working principles and patient-safety screening for X-ray, CT and MRI, including contrast precautions.

Be ready to demonstrate or describe positioning and image-quality evaluation in a practical round.

Keep your radiology qualification documents ready and prepare examples of how you balance image quality with minimal dose.
