The RTM690 system is a small items monitor in a conveyor design for detection of gamma (and beta) contaminated items. The measurement chamber is equipped with gamma plastic scintillation detectors (beta as an option).

The material to be measured such as hard hats, tools or any long items, is continuously transported through the measurement chamber. In case of contamination the conveyor belt stops and rolls backwards.
