Handheld Radiation Monitor PM1401K-3M

DESCRIPTION

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

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. It 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.
