Waste Assay Monitor*

APPLICATION

The WAM-200 measuring facility 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. 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 the subjects 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 the 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
MDG-12S dose rate monitor, direction-dependent, measures the dose rate of the segment in the defined distance from the drum
MDG-02 dose rate monitor measures the background dose rate
Rotary table RS01 and RS02 control and power supply switchboards.
