Evaluation of Complete Blood Counts Parameters of Occupational Radiation and Non-Radiation Professionals from Three Teaching Hospitals in South-South Nigeria

Abstract

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 Key words: Blood cells, Health workers, Ionizing, Radiation..

Ten Years Evaluation of the Relationship Between the Individual Dose of Hospital Workers Occupationally Exposed to X-Rays and its Leukocyte and Platelet Counts of the CBC Tests

“…This worker presented erythema on the hand and face, but the dose estimate did not reach the limits for deterministic effect, not characterizing relational causality. [29] Thus, the present study corroborates what was reported by different authors [5,10,13,23] and national and international organizations [6,8] as it does not identify a p. 16 PAG statistically significant relationship between the leukocyte and platelet counts of CBC tests and the radiation dose levels of HCW in diagnostic and interventional radiology.…”

“…Leukopenia and thrombocytopenia were identified in only 1.09% (95% CI, 0.84 -1.39) of CBC tests for leukocyte count and 2.13% (95% CI, 1.78 -2.53) for platelet count. Association of abnormal immunological responses to accumulated exposure in low doses has no significance as stated in the studies by Forslund et al [21], Gelas et al [22], Zare et al [5] and Orji et al [23].…”
