The Installation and Operation Status of Environmental Sample Analysis System at KOMAC

Korea multi-purpose accelerator complex (KOMAC), which belongs to the Korea Atomic Energy Research Institute (KAERI), has started the performance test operation in the second half of 2013 and currently operates one 20MeV beamline and three 100MeV beamlines. KOMAC's environmental samples analysis system measures the radioactivity of several water samples in the KOMAC site after the test operation period has passed. As a result of measurement with the rainwater and drinking water samples collected from the general area of the KOMAC site, it was confirmed that the measured value is much lower than the effluents control limit. The future operation plan of the environmental sample analysis system is to measure and analyze the environmental radioactivity of the soil or the plant by expending the range of the measurement target sample and analysis. Therefore, sample pretreatment equipment is prepared for this process and for gamma nuclide analysis, searching for the HPGe detector type to satisfy the experimental conditions. KOMAC's environmental sample analysis system operation goal is to build a more systematic sample analysis process and utilize the results of environmental sample analysis as experimental research data and to improve the efficiency of radiation safety management work by monitoring the radiation around the center environment.
