Though it makes a high radiation area in the ring which requires a serious maintenance scheme, a high radiation dose can be applied to the tests of radiation resistible devices. The radiation dose distribution was estimated by using PHITS code, and it was confirmed by dose meas-urements using RadMon, nanoDot OSL dosimeters with continuous monitoring of beam losses. The availability of the radiation test area in the accelerator ring is reported in this paper.
