RESUMEN
Objectives: Ionizing rays used in radiology devices are believed to affect the body tissues of radiology department employees. This study was aimed at comparing the effects of long-term exposure to X-rays on the blood cells of staff working in the radiology departments of several hospitals in the Sulaimani City/Kurdistan region government. Methods: This cross-sectional study was conducted from 2021 to 2022 on 250 employees-including radiologists, radiographers, and other medical staff such as physicians or nurses-in the radiology departments of hospitals in the city of Sulaimani, Kurdistan region government. Data were collected with a questionnaire completed by the participants after verbal consent was provided. Blood samples were collected from 250 radiology staff and sent to a laboratory for measurement of blood parameters. The collected data were analyzed in SPSS version 26 software, and relationships in the data were investigated with descriptive statistical tests, Student's t test, and ANOVA. Results: Most male participants were radiographers with a diploma degree. A statistically significant difference in RBC, HCT %, MCV, and PCT blood parameters was observed between sexes. Moreover, statistically significant differences were observed in RDW-CV and RDW-SD between occupational groups; in mean WBC and lymphocytes among staff who were current, never, or former smokers; and in mean WBC among employees who were current, never, or former drinkers (p < 0.01). Conclusion: Blood parameters such as RDW-CV and RDW-SD were concluded to be affected by job type and X-ray exposure duration.
