[The effect of exposure to radiation and other industrial factors on the morbidity of the personnel in enterprises in the mining and processing of rare-earth metal ores]. / Vozdeistvie radiatsionnykh i drugikh proizvodstvennykh faktorov na zabolevaemost' personala predpriiatii po dobyche i pererabotke rud redkozemel'nykh metallov.

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.
