Citogenetski status u osoba profesionalno izloženih mikrovalnom zračenju GEM radara
Aim of the present study was to analyzed cytogenetic status of workers occupationally exposed to damaging effects of microwave radiation of GEM radar. Microwave radiation of GEM radar acts within microwave field of 10 µ ; W/cm2 to 10 mW/cm2 and frequency range of 1.5 GHz to 10.9 GHz that has contradictory cytogenetic effect on human genome. For that reason we used two methods commonly used in this type of monitoring research: comet assay and micronucleus test. We measured the baseline comet assay effect in whole blood samples and in corresponding unexposed control subjects. It was found that in the subjects who were occupationally exposed to microwave radiation, the levels of DNA damage increased compare to control group and showed interindividual variations. In addition we studied parameters of the micronucleus test were the levels of micronuclei also increased and showed interindividual variations. In addition, new parameters that were measured ; nucleoplasmic bridges and nuclear buds, were detected in exposed group in compare to control group that did not shown this type of damage. All differences between mean group values were statistically significant (P<0.05) in compare to control unexposed group. Results of our study indicate that individuals occupationally exposed to microwave frequency of GEM radar equipment may experience an increased genotoxic risk, emphasizing the importance of individual biomonitoring to prevent any hazard to their health.
