2-channel alarm radiometer NPS-32

The two-channel alarm radiometer NPS-32 is designed to control the dose rate of X-ray and gamma radiation and to signal when the threshold dose is exceeded. Usually, helps to protect passages (driveways) from unauthorized carrying (transportation) of radioactive materials.

The threshold (for each channel separately) is set automatically within 1 minute after the device is turned on.

The threshold value is calculated as Nth = Na + 5σ, where Na is the average number of recorded pulses from the emitter-detector

Package contents:

  • Control and Display Unit (CDU);
  • Network adapter;
  • A radiation detector (1 or 2 units depending on the configuration).

The control and display unit should always be used in heated rooms.
