Методика вибору фільтрів екранування для детекторів Гейгера-мюллера

Abstract

This paper considers a methodology for selecting shielding filters for Geiger–Müller detectors in order to improve the reliability of ionizing radiation measurements. An analysis of the physical processes governing the interaction of radiation with filter materials was carried out, and the influence of their characteristics on the efficiency of detecting different types of particles was investigated. Particular attention was paid to the selection of the material and thickness of shielding filters for the selective attenuation of specific radiation components and the reduction of background interference. An approach to filter selection depending on operating conditions and measurement system requirements is proposed. The obtained results can be used in the development and improvement of dosimetric and radiometric instruments based on Geiger–Müller detectors.
