Sažetak
The alkaline comet assay was employed in the assessment of DNA damage in leukocytes of a worker incidently exposed to gamma radiation (221mSv, Co-60 source). The comet tail lenghts and tail moments were studied. By using the alkaline comet assay immediately after accidental exposure a high level of DNA damage was recordd one day and one week after the radiation incident. Later on, a decrease in both comet parameters was diminished during a one year period, it was still elevated compared to normal values recorded in leukocytes of a healthy, unexposed person.The results, obtained indicate that the alkaline comet assay is a rapid and sensitive microdosimetric technique and is suitable for in vivo human biomonitoring, especially in cases of incidental exposure to ionizing radiation.
