This survey was conducted on radiation hazard in clinical radiation technicians working in health centers, national hospitals, national sanatoriums and some general hospitals (1969). Based on the observation that distrubances in the hemopoietic system are the most pronounced symptoms of radiation hazard, data on blood counts in these workers was satistically evaluated as follows. The average blood count and standard deviation of these blood counts in all radiation technologists in the institutions mentioned above was as follows. WBC 6,298±1,359/mm^3 (1,428 persons), RBC (468±48)×10^4/mm^3 (1,413 persons), and Hb 93.7±9.1% (1,326 persons). Serveral blood tests are conducted every year in radiological technicianl. The yearly fluctuation of cell count was WBC less than 5,000/mm^3 in 36.3% and RBC less than 450×10^4/mm^3 in 66.9%. Classification of blood cell count into normal and abnormal values revealed abnormal values of either RBC or WBC in about one-half of cases. In 131 persons, adnormal values of both were noted. In persons with a history of radiation hazard in the past, the WBC was significantly lower than in those technicians without radiation hazard.
