Abstract :
Background & aim: The biological effects of low doses of gamma radiation have been documented in both humans and animals. The present study aimed to evaluate hematological parameters of individuals exposed to low doses of gamma radiation over an extended period.
Materials & Methods: 50 nuclear medicine technicians with a history of 10 years of gamma radiation exposure and 30 normal hospital staff members were included as the case and control groups, respectively. 5 cc of peripheral blood samples were collected from the participants, and their hematological factors were examined.
Results: Data analysis indicated that the mean hemoglobin showed no significant difference between the two study groups (P-value > 0.05). In contrast, the mean levels of monocytes, eosinophils, hematocrit, MCV, MCH, RDW.SD, PDW, and mean MPV significantly decreased in the radiation-exposed group (P-value < 0.05). Additionally, the mean PCT, PLT, WBC, IG, and lymphocytes significantly increased in the exposed group (P-value < 0.05).
Conclusion: Low doses of gamma radiation affects the blood parameters of individuals exposed to long-term radiation. The results of the current study an be applied to establish new protection procedures or modifying existing ones to enhance the health of nuclear medicine workers.
