Abstract
Radiation monitoring apparatus and methods are classified by main operation characteristics - minimal detectable activity (MDA) and the capability to separately identify nuclides from a mixture of several radionuclides. The lowest MDA per unit volume is achieved by a large-size device (large sample and scintillation crystal) using high-energy γ-photons for the identification of nuclides; MDA strongly depends on the size and effective atomic number of the crystal. If the examined sample contains a number, K, of nuclides, their separate identification without limitation of K can be carried out by the fitting method (the amplitude spectrum of measured signals is expanded over the spectra of separate nuclides). In cases where MDA per unit volume is less important, nuclides can be identified by β-particles and low-energy γ-photons with the use of a compact device - phoswich detector with two scintillation layers strongly differing in thickness and decay time.
