Quality assurance of environmental gamma radiation monitoring in Slovenia

Environmental gamma radiation monitoring established in Slovenia consists of a network of multifunctional gamma monitors (MFMs) based on pairs of GM counters and a network of measuring sites with high sensitive TLD detectors. The measuring points are evenly spread across Slovenia, located at the meteorological stations and more densely on additional locations around the Krško NPP. The MFM network has twofold function with one sensor used for purpose of early warning system in near surroundings of the NPP and the other, more sensitive, for natural radiation monitoring. The paper summarizes some activities to establish quality assurance of the environmental gamma radiation measurements in Slovenia, with a critical view of the results in comparison with the international standards and recommendations. While the results of linearity and energy dependence tests were satisfying, on-field intercomparison showed that the inherent signal of one of the monitors (MFM) has to be taken into account in the range of environmental background radiation.
