The development of the clearance monitor was initiated upon new clearance regulations in Germany for radioactive materials (Radiation Protection Ordinance 2001 §29). The monitor consists out of a mobile detection unit with a measurement volume of 150 liter and an evaluation PC.
Six large area Xenon counter tubes measure both beta and gamma radiation. The approximate 4-pi geometry ensures a high sensitivity and a very good independence of the spatial distribution of the radioactivity in the waste container.
The weight is automatically taken into account by means of an integrated load cell scale. The data are collected in the PC and are stored into a data base.
