Medical observation of the Kozloduy NPP personnel has been carried out for 20 years (1974-1993). The general disease incidence with temporary incapacity of the Kozloduy workers is lower than the general data for the country and workers at thermal power stations in particular. No cases of radiation injuries have been registered. The level of cumulative radiation doses varies from 50 to 620 mSv for the full working period of the personnel. Data about dependence of peripheral blood indicators on the cumulative dose are presented. It is concluded that the health state of the Kozloduy personnel is very good and does not indicate any specific pathology. 5 figs., 2 tabs.
