EFFECTS OF GAMMA RADIATION ON SOME HEMATOLOGICAL PARAMETERS IN FEMALE RATS

The effect of low exposure doses of gamma ray at doses of 0.055 Gy, 0.11 Gy and 0.165 Gy on the some hematological parameters of albino female rats were investigated. At the end of exposure periods and Blood samples were collected for analyses. The results obtained when increases of gamma ray doses of rats caused significant (p ? 0.05) decrease in the RBCs, Hb and Ht%. Also it was found elevation in MCV and MCH with increased exposure dose as well as significant decreases (p? 0.05) Platelets in decreasing with increasing of doses rate and while MCHC% did not change significantly. But it was found when increases of gamma ray doses of rats caused significant (p ? 0.05) decrease in WBCs count, lymphocytes count, monocytic, neutrophils, esinophiles and basophiles respective controls. These findings on the some hematological parameters suggest that the changes in blood parameters of the treated rats were due to the exposure of low doses of gamma ray.
