Abstract:
A Study performed on 30 Iraqi radiation Labors had been exposed tо a low dose tо ionizing radiation at Al-Amal Cancer Hospital in Baghdad the use of three genetic endpoints. Covered 12 females and 18 males between the aged tо (22-57) years. In addition to 20 Healthy individuals from the population, dwelling Baghdad, covered, 7 females and 13 males, aged (19 - 55) years which are non-smokers, non- alcoholic. The cytogenetic analysis, including, HPRT gene mutation¸ comet assay and SCE have been carried out on peripheral blood lymphocytes of labors and control groups. The HPRT gene mutation assay showed a significant increase (p<0.05) in the radiation labors. There were found a significant increase (p<0.05) in comet tail length and tail moment values in thе human lymphocyte in these radiation Labors compared with thе control group. Also the SCE in human lymphocyte for radiation Laborers was significantly (p<0.05) higher than in a control group. Results obtained confirmed the cytogenetic analysis; including, HPRT gene mutation¸ comet assay and SCE are useful as biodosimetric markers for the detection of human exposure to low doses of ionizing radiation. It reflects the simultaneous exposure and actual levels of DNA damage present in radiological laborers' peripheral blood leukocytes by detecting temporary DNA damage and / or repair activity.
