Radiation Effects (ICRP60 – 1991)

• Somatic: they affect the health of the irradiated person. Mainly different kinds of cancer (leukemia is the most common, with a delay period of 2-5 years, but also colon, lung, stomach cancer…).

• Hereditary: (genetic) affect the health of the offspring of the irradiated person. Mainly mutations that cause malformation of any kind.

• Antenatal: somatic and hereditary; expressed in the foetus (more sensitive than the adult), in the live born or descendants. The type of effect depends on the time of irradiation and development: abortion-mental retardation- malformation → threshold dose. Cancer risk similar to that following irradiation in early childhood. (ICRP 103)
