Radiation Detectors Set PM1403

Multifunctional, networked mobile monitor for measuring all types of ionizing radiation and spectrum collection of gamma emitting sources.

The device is equipped with a built-in CsI(TI) detector for detection and location of gamma radiation sources and reliable identification of radioisotopes. In addition, the device has five external interchangeable modules for detection of alpha, beta, gamma and neutron radiation.

The device provides fast and reliable identification of radioisotopes and can transmit measured radiological data and geographic coordinates to the Remote Expert Center of the Polimaster Nuclear Protection Network system (Polimaster NPNET™) via buit-in GSM/GPRS modules.

where to buy

This highly versatile handheld radiation monitor combines features of Personal Radiation Detector, Dosimeter/radiometer and radionuclide identifier with fast and reliable identification of radioisotopes that does not require connection to an external device (pocket PC/laptop/IPaq, etc.) for radiological data processing and analysis.

The Personal Radiation Detector /Dosimeter allows radionuclide identification, despite the weakening and scattering effect of shields, containers or other forms of physical protection of radiation sources. The results are shown on a bright, easily read color LCD display.

The device combines the functionality of a dosimeter with that of a radiometer, offering spectroscopic radionuclide identification and wireless integration with radiation portal monitors РМ5000А, PM5000B, (which are designed for installation at customs, in airports and border checkpoints to prevent the illicit trafficking of nuclear and radioactive materials).

The instrument’s functionality includes wireless integration into the Polimaster Nuclear Protection Network (Polimaster NPNET™). Radiological data and geographic coordinates are transferred to the Remote Expert Center via built-in GSM /GPRS modules, allowing to generate a unified report of the investigated radiation incident. This provides a complete solution for various tasks of radiation safety and control.

PM1403 has various configurations, depending on the user needs. Processing unit in combination with one or several detectors is called Radiation Detectors Set. Radiation Detectors Set may also include accessoires: handle, telescopic extension tube, clamp, cables, bracket etc.
