[The assessment of combined exposure to radiation and chemical factors based on the study of the morbidity of personnel in radiation-chemical manufacture].

The study analyzed the work conditions of personnel engaged into production of plastic modified by radiation. The analysis revealed that the staffers exposed to combined action of radiation and chemical factors face 6 times more intensive harm from radiation resulting in more cardiovascular diseases. All that should be considered in setting the norms for annual radiation doses at workplaces. Real production demands maximal allowable dose to equal 1 rem/year, if the personnel is exposed to chemicals (ozone, nitrogen oxides, ethylene, formaldehyde, acrolein). The scientist elaborated a method to evaluate combined action of chemicals and radiation, which is based on dependence of morbidity on personnel's age. During the further calculation of summarized factor all previous parameters are added, given their enhance.
