The RTM644Inc system is an industry leading clearance monitor for large objects such as palettes, waste bags, grid boxes, 200 l and/or 400 l drums checking for gamma radiation. The goods to be measured are moved into the chamber by a conveyor system.

24 large-area gamma-plastic-scintillation detectors are arranged in 4π geometry ensuring high sensitivity and low detection limits. Geometry and weight of goods are considered, compensating self-shielding effects.

Measurement parameters can be matched to specific requirements.
