ASSESSMENT OF IMPACTS OF HEMATOLOGICAL PARAMETERS OF CHRONIC IONIZING RADIATION EXPOSED WORKERS IN HOSPITALS
This study examined the impact on hematological parameters for medical workers that work on ionizing radiation equipment. Comparison of mean values of CBC (complete blood count) parameters with the normal range and comparisons based on the T-tests between radiation exposed (RE) workers and radiation unexposed workers was done. Most of the parameters were below the normal range and were disturbed in majority of the RE workers. Most affected parameter was MCH (mean corpuscular hemoglobin) which was found to be lower in majority of radiotherapy workers. From T-test, statistically significant differences (p<0.05) were observed in the mean values MCHC (MCH concentration) and lymphocytes (LYM). A decline was observed in plateletcount, hematocrit and lymphocytes, whereas, an increase was observed in neutrophils in association with Annual average effectived dose (AAED) (0.29-1.91) mSv. These associations were although weak but significant. Long term work on radiations at even low doses (<20 mSv) can impact health and results into an altered immune response or anemia.
