Question 11 • Physics

Which are methods of reducing exposure to ionizing radiation? Choose three correct answers.

Answer
A
using a short burst of X-rays to take an image
B
taking an X-ray image of large areas of the body at once
C
picking up radioactive material by hand to avoid dropping it
D
taking an image of the smallest possible area
E
using a lead apron during medical X-rays

Explanation

Reducing exposure means limiting the time exposed, the area exposed, and shielding the body. A short burst of X-rays reduces the time of exposure, while imaging the smallest possible area avoids exposing unnecessary parts of the body. A lead apron provides shielding; taking large-area images or handling radioactive material directly would increase exposure.
