[Some health parameters in personnel contacting highly enriched uranium].

The authors analysed 20-years and longer observations over health state of personnel having occupational contact with highly enriched uranium. Findings are no determined effects as clinical manifestations of chronic uranium intoxication, presented by most frequently involved systems (hemopoietic, bronchopulmonary) and main organs accumulating uranium (liver, kidneys, bones). Long-term observations revealed malignancies in 11% of the examinees. Further medical observations over the personnel (risk group) are required to evaluate risk of aleatory effects in prolonged contact with various uranium compounds.

Multivariate regression analysis proved that radiation of allowable level had no unfavorable influence on morbidity with transitory disablement. Increased from 0.15 to 2.0 microGy/hr dose rate of gamma radiation at the workplaces resulted in slightly lower morbidity. Unfavorable influence on morbidity was caused by physical factors (noise, vibration, microclimate, work hardness), irritating and neurotoxic chemicals in amounts which seldom exceeded the allowable norms, hostile climate and geographic conditions.
