Sažetak
Within the process of cigarettes manufacturing, tobacco paper thickness is controlled using closed radioactive source, i.e.strontium-90. On that ground, the question of possible health imapct of such an occupational exposure was risen. Accoding to the codes of practice exercised within the radiation protection frame, all workers dealing with strontium-90 have been provided with personal film-dosemeters, collected and read out in regular 3 month intervals by an authorised institution. RThe workers in question are also placed under regular medical surveillance carried out by the local Occupational Medicine Services. Since radioactive sources are also assumed to have a certain genotoxic impact, such an assumption was verified using single cell gel electrophoresis (SCGE). The study embraced a total of 20 workers dealing with strontium-90, out of which 12 males and 8 females, aged 39.6 years on the average (range 20-61 years), with an average duration of employment of 20.3 years (range 3-38 years). Over the entire follow-up periodm physical dosimetry unexceptionally revealed doses falling bellow the detectibility range. Medical reports revealed no clinically significant changes in overall health status. SCGE revealed no signs of strontium-90 genotpxicity (mean tail lenght ranging from 10.37 to 15.85 um). Results obtained by this survey provided no reason whatsoever to believe that strontium-90, present in such an occupational setting, poses as a health risk. However, constant ambient and biomonitoring of the exposed personnel, and close observation of all the established codes of conduct regarding radioactive sources, should be neglected at any time.
