The Effect of X-Ray Radiationon Hematopoietic Tissue Among Radiology Technologists

Background:Long-term exposure to low doses of ionizing radiation may affect cells and tissues and results in various adverse health effects. Objectives:In this study the purpose is to detect the blood cells count which reflects of the changes that may happen in bone marrow of X-ray technologists.Materials and Methods:The present study is conducted in Khartoum state hospitals during the year of 2011. The sample size was 95 male volunteers represented radiology technologists working in Khartoum state hospitals with age range 23-57 years.Technologists are classified according to duration of exposure.The samples are tested for hematology parameters by cell counter. Results:The mean value of leucocytes, neutrophil and lymphocyte count is significantly decreased (p<0.05) in X-ray technologists on duration of exposure between 10-15 years, while X-ray technologists on duration of exposure greater than15 years showed significant decrease (p<0.01) when compared to controls. However, no significant difference is observed in red blood count, hemoglobin, and mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration, hematocrit and eosinophil + basophil count between the groups.Conclusion:Hematopoietic system of X-ray technologist is affected by long duration of low dose of X-ray exposure resulting in depression peripheral white blood cells count
