Contamination monitor for bags with removable detectors
Monitor for fast measurement of the gamma activity of bags with potentially contaminated material, compared with the clearance limits. Two large plastic scintillators slide as close to the bag as possible on an anti-vibration base with scale, and the detectors can be removed and used remotely, battery-powered with data over Wi-Fi. The monitor is on wheels and easy to decontaminate.
