dc.description.abstractIn 2020, the radiation level caused by gamma radiation at the site boundary of COVRA N.V., the Central Organisation for Radioactive Waste, was below the maximum permitted level of 40 microsievert per year. The maximum annual gamma dose is 3.2 microsievert. This is the level found by the analysis of measurements carried out by RIVM. RIVM is tasked by the Authority of Nuclear Safety and Radiation Protection (ANVS) to report annually on whether COVRA N.V. meets the criterion specified in its operating license. COVRA N.V. is required to ensure that the maximum effective dose received by persons outside the site boundary of COVRA N.V. does not exceed 40 microsievert annually, as specified in its operating license. In order to determine the maximum effective dose, gamma radiation is measured at twelve locations along the site boundary. The measurements are carried out within the framework of the MONET monitoring network, which falls under the administrative management of the RIVM. The measurements are analysed by subtracting the natural background value. The resulting measurement data are corrected using the Actuele Blootstelling Correctiefactor (or ABC factor, meaning actual exposure correction factor). An ABC factor takes into account the specific use of the area where exposure to the gamma dose may occur. This translates into a maximum effective dose of 3.2 microsievert per year, which is below the maximum permitted annual gamma dose. This report provides the daily averages of the radiation dose recorded by the MONET monitors at the boundary of the COVRA N.V. site in 2020, and explains how the background level at each measuring location was determined.
