Introduction: Radiation workers are exposed to chronic effects due to long-term exposure to low levels of ionizing radiation. One of the biological indicators to evaluate these chronic radiation effects is the study of the hematopoietic system. The purpose of this study is to compare the changes in blood parameters of radiology staff and staff of other wards of the hospital.Methods and Materials: In this study, ۴۷ radiology staff working in the radiology department of the hospital as the study group and ۹۸ personnel in other departments as the control group were included. Demographic data including age, gender and work experience were obtained. Hematological parameters were extracted from complete blood count tests of participants.Results: The results of this study showed that the parameters MCH and MCHC were significantly decreased in male study group, whereas no significant differences were observed in blood parameters of female study group in comparison to those of control group. There was significant positive correlation between parameter Hgb and age. There was significant negative correlation between work experience and WBC, while there was significant positive correlation between work experience and Hgb.Conclusion: Based on the results of this study and other studies, it can be concluded that long-term exposure to low levels of radiation may change blood parameters. Therefore, regular and periodic complete blood count test along with absorbed dose monitoring of radiation workers is recommended.
