The FRM-02 monitors are intended for measuring and analysing the total activity of gamma-emitting radionuclides in waste stored in standard crates or drums. Based on the measurement results, it is possible to make a decision on whether the material is to be free released or not. It is primarily used in the dismantling and decommissioning of nuclear facilities. As standard, large area scintillation detectors in 4π geometry are used, which are located in the door, back panel, top and bottom panels and the side panels of the shielded measurement chamber. The number of detectors allows for a fast measurement and an accurate determination of the activity’s space distribution.
