Operation Principle

Instrument performs continuous measurement of ambient dose equivalent rate of gamma and X-ray radiation in the wide energy range, monitors alpha, beta and neutron (PM1401K-3, PM1401K-3P, PM1401K-3E) radiation, operates as spectrometer of gamma radiation and radioisotope identifier (PM1401K-3, PM1401K-3P, PM1401K-3M), and measures food/soil contamination with ¹³⁷Cs radionuclide (PM1401K-3, PM1401K-3M, PM1401K-3P).

Instrument is equipped with built-in audible and visual alarms, GPS module, USB interface for PC communication. Non-volatile memory allows recording and storing up to 10 000 events. PM1401K-3 has compact size and lightweight, bright and color LCD, shockproof hermetic case and can be used in both indoor and outdoor environments.

Modifications:

РМ1401К-3 – basic model is equipped with built-in alpha, beta, gamma and neutron detectors;
РМ1401К-3М – modification is equipped with built-in alpha, beta and gamma detectors, without neutron detection capabilities;
РМ1401К-3P – modification is equipped with built-in alpha, beta, gamma and neutron (based on three scintillation units) detectors;
PM1401K-3E – gamma-neutron modification without functions of ¹³⁷Cs activity measurement and radionuclides identification.
