Research Center for Safety, Metrology, and Nuclear Quality Technology (PRTKMMN)-National Research and Innovation Agency (BRIN) had coordinated a national inter-laboratory comparison of 152Eu source activity measurements in Indonesia. The aim of this inter-laboratory comparison was to investigate the abilities of laboratories monitoring, to obtain information on the quality of radionuclide activity measurements , to determine equipment performance and to improve the quality of radioactivity metrology in Indonesia. Twenty four radioactivity laboratories participated in these comparisons. The measurement results were evaluated using percentage differences of relative deviations (%), value of activity concentration ratio (R) and value of equality or activity measurement proportionality between Standardization Radionuclide Laboratory PRTKMMN and participant laboratories in Indonesia (En numbers criteria). The majority of the result were considered to be satisfactory because there were within the acceptable limits.
