Operation principle

The PM1401K-3P continuously measures ambient dose equivalent rate Ḣ*(10) of photon radiation in the wide energy range, detects alpha, beta, gamma, and neutron radiation, measures alpha and beta radiation flux density, operates as a gamma radiation spectrometer and radioisotope identifier, and measures food/soil contamination with¹³⁷Cs radionuclide.
