title: Hematological findings in male x-ray technicians.
abstract: OBJECTIVE
  In view of the known health hazards of x-ray radiation, this study focuses on the basic hematological parameters: red blood cells (RBCs), white blood cells (WBCs) and platelets count in x-ray technicians. The aim was to identify the affect of x-ray radiation on blood cell counts in x-ray technicians.
  
  
  METHODS
  The present study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the year 2002. In this study, a group of 40 apparently healthy male x-ray technicians with age ranging from 25-50-years were recruited. They were matched with another group of 40 apparently healthy control subjects in terms of age, sex and ethnic origin. Both groups met with exclusion criteria as per standard. Red blood cells, WBC and platelets count were performed by using a blood cell auto analyser (Beckman coulter counter).
  
  
  RESULTS
  The mean value of platelet count was significantly decreased (p<0.01) in x-ray technicians when compared to controls. However, no significant difference was observed in RBC and WBC count between the groups.
  
  
  CONCLUSIONS
  The present study suggests that exposure to x-ray radiation causes decreased platelet count. Further, studies are needed to study the long-term effects of x-ray radiation on blood cell count in x-ray technicians.
