NEET BIOLOGY

Detailed explanation-1: -Ionizing radiation damages the genetic material in reproductive cells and results in mutations that are transmitted from generation to generation.

Detailed explanation-2: -Ionizing radiation induces gene mutations (point mutations, deletions and insertions) as well as chromosome damage in mammalian cells.

Detailed explanation-3: -Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.

Detailed explanation-4: -The risk of genetic mutation is expressed in terms of the doubling dose: the amount of radiation that would cause additional mutations equal in number to those that already occur naturally from all causes, thereby doubling the naturally occurring rate of mutation.

Detailed explanation-5: -Ionizing activity can alter molecules within the cells of our body. That action may cause eventual harm (such as cancer). Intense exposures to ionizing radiation may produce skin or tissue damage.
