Question 19
F

A radioactive implant that emits beta radiation is placed inside a tumour to destroy the tumour cells. Why is beta radiation suitable for this use?

[1]
A

It passes out of the patient, so the treatment can be monitored from outside

B

It travels only a short distance in tissue, so nearby healthy cells are spared

C

It is the least ionising of the three types, so it damages very few of the cells

D

It has a very long range in tissue, so the whole tumour is treated at one time
