FRM-02 monitors are designed to measure and analyze gamma-emitting radionuclides in the release of material from nuclear power plants to the environment.
Based on the measurement results, it is possible to decide whether the material will be intended to be released into the environment, decontaminated, or stored as radioactive waste.
FRM-02 consists of the following basic parts:

  • Measuring chamber with plastic scintillation detectors with lead shielding
  • Embedded tensometric scale sensors for material weighing
  • Drives for handling measured containers
  • Large information display panel and a visual-acoustic signalling unit
  • Safety closures and interlocks to maximize the occupational safety
Product design and specifications are subject to change without prior notice or obligation.
