Question

State whether the following statement is true or false.

Non-ionising radiations have high penetrability.

Answer 1

This statement is false.

Explanation:

Non-ionising radiations, such as UV rays, have relatively lower energy compared to ionising radiations like X-rays or gamma rays, and therefore have lower penetrability. Ionising radiations can penetrate deeply into biological tissues, whereas non-ionising radiations have limited penetration power. For example, UV rays primarily affect surface parts like skin and cornea and do not penetrate deeply into the body.
