A hospital uses X-rays to produce an image of a patient's broken bone. The same hospital uses gamma rays to treat a patient who has cancer.
Give one other medical application of gamma rays.
The radiographer who operates the X-ray machine stands behind a lead screen while each image is taken. Explain why.
The patient with the broken bone has only one X-ray image taken. Suggest why the doctor decides that the benefit to this patient is greater than the risk.
