Purpose: Revealing a group of persons with the raised risk of ischemic stroke by the method of screening analysis.

Material and methods: In this research 426 (161 woman and 265 men) workers of the Bilibinsky nuclear power station took part. In the professional aspect the studied contingent is presented as by both operation personnel (heads, operators, process engineers, etc.), i.e. persons mainly carrying out brainwork, and technicians (electromechanics, electrical engineers, mechanics, welders, electric welders, etc.), i.e. persons mainly carrying out manual labor. All surveyed have being exposed to small doses of ionizing radiation within permissible values and subjected to psycho-emotional pressure. In this work the screening analysis system with the use of 5-factorsFramingemsky scale was applied.

Results: It was found that 141 persons of 426 (33. 1%) had the raised risk of ischemic stroke. The most subjected to the risk of ischemic stroke was the 45–49 age group Arterial pressure and smoking were dominating risk factors. Hypercholesternaemia was the least significant risk factor in all age groups, both men and women. According to medical out-patient cards, in the group of raised risk (141 persons) only two had the cerebral vascular diseases diagnosis. 91 people have 1–2 degree arterial hypertension, the rest 48 persons did not have any diseases leading to vascular pathology of the brain or were practically healthy. This publication is the first in a series of articles on comparative risk estimation of brain vascular diseases of personnel of the nuclear power stations located in various regions of the Russian Federation.
