Question

how can damage to living things occur from exposure to x - rays or gamma rays?
a. atoms and molecules in the body can be ionized.
b. the human body can overheat.
c. the human body can give off thermal energy.
d. bad cases of sunburn can occur.

Explanation:

X - rays and gamma rays are ionizing radiations. They have enough energy to remove tightly - bound electrons from atoms and molecules in the body, causing ionization which can damage biological tissues. Overheating, giving off thermal energy, and sunburn are not the main ways damage occurs from X - rays or gamma rays.

Answer:

A. Atoms and molecules in the body can be ionized.
