Background: The exposure of radiation workers to ionizing radiations, especially in medical field has increased due to the use of advance technological equipment in the diagnostic radiology and radiotherapy departments. This study is aimed at evaluating the effects of ionizing radiation on CBC parameters of medical radiation workers in South-South, Nigeria.
Materials and Methods: This comparative cross-sectional study was conducted in three teaching hospitals to include 39 radiation workers and 39 non-radiation workers with same year of working experience of one year to 10 years.
Results: The mean values for CBC in DSUTH are; radiation workers (WBC: 6.41, RBC= 5.47, Platelet = 240.28, Hb = 13.64 and Lymphocyte = 27.86) and non-radiation workers (WBC= 6.41, RBC= 5.47, Platelet = 250.75, Hb = 13.63 and Lymphocyte = 27.78).There were no statistically significance differences in the mean values of CBC in radiation and non-radiation workers in DSUTH (p > 0.05). There were no statistically significance differences in the mean values of CBC in radiation and non-radiation workers in NDUTH (p > 0.05).
Conclusion: Complete blood cells parameters only cannot be used as the most reliable indices for evaluating radiation biological risks associated with long term exposure, as we found that there was no statistically significant mean difference of CBC in radiation workers and non-radiation workers
