Vedclass · Answer

(B) Non-ionising radiation refers to electromagnetic radiation that does not have enough energy to remove electrons from atoms or molecules. $UV$ (Ultraviolet) rays are a form of non-ionising radiation. Although they are non-ionising,$UV$ rays have sufficient energy to cause chemical changes in biological molecules. Specifically,$UV$ rays,particularly $UV-B$,are absorbed by $DNA$ and cause the formation of pyrimidine dimers (such as thymine dimers),which lead to mutations and damage to the genetic material.
