A radiographer wears a protective apron lined with lead when taking X-ray scans of a patient.
Why does the radiographer wear an apron containing lead?
To prevent the patient's X-rays from being scattered.
To reduce the radiographer's exposure to ionising radiation.
To reflect the X-rays back towards the patient's body.
To help the radiographer maintain a stable body temperature.
