Gamma ray measuring system WAM

for radioactive waste

Application The WAM measuring system is intended for the measurement and the determination of nuclear waste activities, activity concentrations, total activities and total activity concentrations of the selected radionuclides which emit gamma radiation in a range from 100 to 1500 keV. Total activities are the sum of activities of individual radionuclides; and total activity concentrations are the sum of all activity concentrations of individual radionuclides. Solids and materials with an average density up to 2500 kg/m3 located in the standard drums with a volume of about 0.2 m3 are measured. Features The WAM (Waste Assay Monitor) is a complex measuring system which is intended for the monitoring of radioactive waste in standard 200-litre drums. WAM involves the following systems: • - Monitor – a fixed segmented gamma-spectrometric monitor for the determination of activities of selected radionuclides in the individual drum segments with vertical motion and collimator • - Transfer system is used for moving the measuring part from/to the drum measured • - Dose rate monitor, direction-dependent, measures the dose rate of the segment in the defined distance from the drum • - Dose rate monitor measures the background dose rate • - Rotary table, control and power supply switchboards DESCRIPTION The WAM measuring system is intended for the measurement and the determination of activities, activity concentrations, total activities and total activity concentrations of the selected radionuclides which emit gamma radiation in a range from 100 to 1500 keV.
