Abstract
It is necessary to efficiently manage and operate the irradiation facilities which are used for the various basic and practical application studies as well as for the industrialization of the radiation technology. Dose distribution measurements were carried out to calculate the accurate irradiation dose as our high intensity gamma irradiator was dismantled in Seoul and re-installed in Taejon. The irradiator was operated for the purpose of researches on radiation-related technology and irradiation service after getting approval from KINS. Dose distribution on the irradiation table installed on the northern side of the high intensity gamma irradiator was measured using 137 red acrylic dosimeters and 425 ceric-cerous dosimeters. The data were used for the accurate irradiation of samples. The average dose, standard deviation of dose and deviation rate of dose on the various positions were calculated to identify the variation of dose uniformity caused by the difference in sample size. Our ceric-cerous dosimeter was calibrated through IAEA international dose assurance service. It was reported that our dosimeter showed comparatively low error of -4.05%. On the basis of the results, the correction factor for the dosimeter system could be determined. The high intensity gamma irradiator operated for 290.7 hours for dose distribution measurement,

The irradiator was operated 31 times to irradiate 17 different kinds of sample from 6 research groups and 3 domestic companies. The low intensity gamma irradiator was designed and its safety against imaginary accident was confirmed by computer analysis.}
