The aim of the paper is to investigate effects of long term x-ray exposure on the human lymphocyte, reactive lymphocyte parameters and morphology of lymphocytes in x-ray technicians at Kirkuk hospitals. The study included 54 apparently healthy male x-ray technicians were matched with another 54 apparently healthy control to show any alteration in the lymphocytes, reactive lymphocytes and morphology. The investigated samples were divide into two groups depending on the work experience and working hours per day. The samples were tested for hematological parameters by complete blood cells count (CBC). The results showed that strong significant (P<0.0001) increasing was recorded for the reactive lymphocytes in all groups of the diagnostic technicians compared with their controls and significantly increasing of lymphocytes observed for some groups. It was concluded that chronic exposure of x-ray can vary lymphocyte and reactive lymphocyte parameters significantly and working hours per day have discernible effects on lymphocyte morphology.
