genetic effects of radiation

Also found in: Dictionary, Thesaurus, Encyclopedia.

genetic effects of radiation (jənet´ik), the changes produced in the individual's genes and chromosomes of all nucleated body cells, both somatic and gonadal, due to exposure to radiation. The more common meaning relates to the effect produced in the reproductive cells. Radiation received by the gonads before the end of the reproductive period has the potential to add to the number of undesirable genes present in the population.
