Description

Office of Atoms for Peace (OAP), as the national regulatory body of Thailand, has initiated project on “Biological Effects of Ionizing Radiation in Public and Occupational Staff in Northern and Northeastern of Thailand. The objectives of the 5 years project are (1) to have completed database of radioactive materials and radioactive sources in Thailand (2) to validate method for measurement of ionizing radiation effects in public and medical staff, and (3) to access risk of staff in medical centers exposed to ionizing radiation. Briefly, dose-response curve of dicentric analysis assay from non-medical and medical staff with Co-60 sources has been established and demonstrated correlation of irradiated dose to human blood and frequency of aberrated chromosomes. It is found that all staff is safe at occupational doses. The results are in agreement with the previous study of irradiated Cs-137 and Co-60 from 0.1 Gy to 5 Gy performed by Department of Applied Radiation and Isotopes, Faculty of Science, Kasetsart University and Department of Pathology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University and OAP, respectively. However, those dose-response curves should be further developed and validated for in vitro dose reconstruction in medical management in cases of radiological emergency in the country.
Keywords: bio-dose, dosimetry, low dose
