Vedclass · Answer

(B) Non-ionizing radiation refers to electromagnetic radiation that does not have enough energy to remove electrons from atoms or molecules. $U.V.$ (Ultraviolet) rays are a classic example of non-ionizing radiation. Although they are non-ionizing,$U.V.$ rays have enough energy to cause chemical changes in biological molecules. Specifically,$U.V.$ radiation,particularly $U.V.-B$,is absorbed by $DNA$,which causes the formation of pyrimidine dimers (such as thymine dimers). This damage disrupts the structure of $DNA$ and can lead to mutations or cell death. In contrast,$X$-rays,Gamma rays,and Beta rays are all forms of ionizing radiation.

Which of the following non-ionizing radiations causes damage to $DNA$?
