Multipurpose Hand-Held Radiation Monitor/Identifier - РМ1401К-3/M

Zoom

PM1401K-3 Multipurpose Hand-Held Radiation Monitor/Identifier belongs to the new family of Polimaster extremely sensitive and compact multipurpose hand-held radiation monitors.

PM1401K-3 can continuously measure ambient dose equivalent rate Ḣ*(10) of gamma and x-ray radiation in the wide energy range, monitor alpha, beta and neutron radiations, work as spectrometer of gamma radiation and radioisotope identifier, and measure food/soil contamination by 137Cs radionuclide.

All operation history is stored in the instrument’s non-volatile memory and may be downloaded to a personal computer through a USB interface. PM1401K-3 is also equipped with built-in GPS to enable geocached data logging.

The instrument can be used in both indoor and outdoor environments and is intended for everyday and/or emergency use by firefighters, military, police and other first responding agencies.

where

РМ1401К-3 instruments are available in four modifications:

  • РМ1401К-3 – is a base model of the instrument. It uses 3He tube for detection and registration of neutron radiation.
  • РМ1401К-3М – is a gamma-only model of the instrument without neutron detection capabilities.
  • РМ1401К-3A - is a model  of the instrument that uses small volume 6LiI(Eu) neutron detector. However its neutron sensitivity is selected to comply with ANSI 42.32 requirements for PRDs.
  • РМ1401К-3P - is a model of the instrument that uses 6LiI(Eu) scintillator based neutron detector which neutron sensitivity is similar to the base model PM1401K-3.

 

 

Key features:

  • Detection, search and localization of α-, β-,γ- and neutron radiation sources
  • Measurement of ambient dose equivalent rate Ḣ*(10) of gamma and x-ray radiation
