Description

This paper describes γ reference radiation fields established by the authors, with radiation protection level, and its determination and evaluation. The Air Kerma Rate which is 1 meter from the source was measured. The results show that uncertainties of Air Kerma Rate are less than 4.6% for 137Cs (18.5 GBq), 4.6% for 137Cs (74 GBq), 4.2% for 60Co(37 GBq). The size of radiation field and its uniformity were also measured. These results show that scattering radiation and uniformity of radiation field accord with the ISO 4037. (authors)
