Which statement best describes the effect of beta particles on body tissue?
a.) they cause more damage than gamma rays but less than alpha particles.
b.) they cause more damage than alpha rays and gamma rays combined.
c.) they cause more damage than alpha particles but less than gamma rays.

The correct answer is option C.

Explanation:

Alpha radiations are emitted by alpha particles imparts less amount of energy to the absorbing material.

Where as beta radiation by beta particles are more penetrating than the alpha particles and gamma rays are most penetrating radiations they can even penetrate through out a human body.

The order of penetration of these radiations from least to most is :

Alpha rays < Beta rays < gamma rays

Hence, the correct answer is option C.
