[Estimated number of expected stochastic changes in the population occupationally exposed to X-rays].

In this paper the life-time effective dose equivalent and expected postradiation stochastic effects number in various subpopulations occupationally exposed to X-rays have been estimated. The prognosis of life-time doses absorbed by those occupationally exposed to X-rays and the relationship between the effective dose equivalent and surface exposure dose registered in the individual dosimetry system constituted the basis for this evaluation. The obtained results indicate that under the present X-ray exposure conditions the probability of the occurrence of X-ray adverse health effects in form of post-radiation cancers is insignificantly low.
