Effects of radiation on the human impact
1. Somatic (bodily) – is formed in the body of
an irradiated man.
2. Genetic – is related to the damage of a
genetic apparatus and manifests itself in
generations of an irradiated person: in
children, grandchildren, grandsons and in
other more further posterities
