Dynamics of oncological sick rate among a population of some districts of Semipalatinsk region exposed to irradiation by nuclear explosions conditions

The dynamics of oncological sick rate among Semipalatinsk region population is analyzed. There where two groups (control and principle) of irradiated personnel for the period from 1956 to 1994 . In the each of croup there were about 10000 men. The principle group have got different doses of both the internal and external irradiation because of the nuclear tests on Semipalatinsk test site. The equivalent weighted mean dose in principle group is 200 c rem, and in the control one - 7 c rem. The yearly tempo of oncological sick rate in principle group exceeds control one to 5,6 times during of the first peak. The higher susceptibility has been marked for tumors of the gastrointestinal tract (cancer of esophagus, stomach, liver). Among of other localization the higher susceptibility are a cancer of lung, mammary and thyroid glands
