Gamma-only model without a neutron detector.

The PM1401K-3 series of radiation monitors compromises a wide range of all-in-one devices for radiation detection, dose rate, contamination measurements, spectrometry, and radionuclide identification. 

The PM1401K-3M model is a gamma-only radiation monitor without a neutron detector. The instrument is designed for quick and reliable measurement of gamma dose rate, detection of alpha, beta, and gamma sources, measurement of alpha and beta radiation flux density, acquisition of gamma spectra, identification of radioisotopes, and measurement of food/soil contamination with 137Cs.

Features

  • Storage of up to 10000 events and 1000 spectra 
  • Audible, visual, and external vibration alarm 
  • Categorization of identified radionuclides 
  • Shock and water-resistant IP65 case 
  • Adjustable radionuclide libraries 
  • USB communication with PC 
  • Built-in GPS module

Applications

  • Customs and border control
  • HAZMAT and CBRNe teams
  • Emergency services
  • Police and security
  • Industrial facilities
  • First responders

Operation principle

The PM1401K-3M continuously measures ambient dose equivalent rate Ḣ*(10) of photon radiation in the wide energy range, detects alpha, beta, and gamma radiation, measures alpha and beta radiation flux density, operates as a gamma radiation spectrometer and radioisotope identifier, and measures food/soil contamination with 137Cs radionuclide.
