Portable Radiation Monitor РМ1402М (full set)

A portable multipurpose radiation laboratory which consists of a processing unit and five external exchangeable radiation detectors.

PM1402M can be used for detection and measurement of the alpha, beta, gamma and neutron radiation and gamma spectrum accumulation.

where to buy

The PM1402M is a portable multipurpose radiation monitor designed for field use to measure all types of ionizing radiation and spectrum collection of the gamma emitting sources. The device consists of a processing unit and set of five external exchangeable detectors.

The small size and low weight of the processing unit allows easy carrying in the field, since it can be placed in a pocket or on a utility belt.

The full set includes:

  • Processing Unit
  • Gamma Radiation Detector BD-01 - based on CsI(Tl) detector, for search of gamma radiation sources
  • Gamma Radiation Detector BD-02 - based on CsI(Tl) detector
  • Gamma Radiation Detector BD-03 - based on GM-counter, for measurement of ambient equivalent dose rate of X-ray and gamma radiation
  • Gamma Radiation Detector BD-03-01 - based on GM-counter
  • Neutron Radiation Detector BD-04 - based on 3H, for search and location of the neutron radiation sources
  • Alpha and Beta Radiation Detector BD-05, for evaluation of the alpha and beta contamination levels

 

The processing unit features a 512 channel analyzer with storage capacity for 110 spectra in its non-volatile memory. The spectra can be downloaded to a PC via RS-232 data port for further data processing and/or radioisotope identification.

The portable radiation monitor is equipped with audible and vibration alarms to alert a user of the presence of a radiation source.

Additionally, the PM1402M is supplied with a telescopic extension tube which is used for detector mounting, inspection of difficult-to-access areas and/or protection of the user from the irradiation exposure by distance.
