Protection of nuclear facility and nuclear power plant personnel requires thorough, frequent monitoring for gamma contamination using a detection system that won’t disrupt plant operations. The Thermo Scientific™ PM12 Personnel Gamma Portal Monitor provides simplified but advanced monitoring capability for workers, articles and waste well below clearance levels. The unit has eight identical large gamma-sensitive plastic scintillation detectors to provide coverage from head to feet and accomodates traffic flow in either direction for reliable radiation detection in an efficiently-running process.

The PM12 Personnel Gamma Portal Monitor features eight identical, large gamma-sensitive plastic scintillation detectors; three detector assemblies are located in each side of the portal, with additional detectors to monitor the head and feet. The monitor may be used in five modes: walk-through, one step, two step, three step, stand and turn.

  • Operates in minimum count time or maximum sensitivity mode.
  • Checks individual detectors levels.
  • Continuously checks for changing background levels during the measurement.
  • Vertical system lights are located on both sides of the portal frame indicate operational status.
