The quantity and leukocytes components as biological dosimeters on the radiation workers at Radiology Installation Sanglah General Hospital Denpasar, Bali-Indonesia

Introduction: Radiation monitoring program is applied to all the radiation workers using physical dosimeter, in the TLD form, badge films, and others. The monitoring of the biological aspect is called biological dosimeter as an indicator of the organ damages that caused radiation exposure, especially on the radiation workers in the radiology installation Sanglah General Hospital are not much studied.These study aims are determining the quantity and leukocytes components differences that caused environmental radiation exposure in direct contact radiation and direct non-contact radiation workers. Method: The research data was obtained through the blood test at Sanglah General Hospital Denpasar with diffraction count method. The extent of the leukocyte component is determined by the absolute count method. The population in this study were 70 people with the total sample were 35 direct radiation workers (30 radiographer people, five medical physicists) and 35 direct non-contact radiation workers (12 nurses, 18 administrative personnel, five medical records). Results: All the blood cell quantity values (hemoglobin-HGB, RBC-erythrocyte, leukocyte-WBC), as well as the percentage of WBC components (basophil-Baso, eosinophil-Eos, Neotropifil-Neo, lymphocytes -Limfo and Monocyte-Mono) for radiation workers and non-radiation workersare in the normal range. However, there is a significant difference in hemoglobin component between radiation workers and non-radiation workers, others blood parameter (RBC, WBC, and leukocyte component) doesn’t show any significant difference between two group worker. Conclusions: Long time in the radiationfield area which increases the deterministic effect the cells of the human bodyresponse. Primarily, biological indicators of radiation as a dosimeter are used.
