Application and Development of Noncontact Detection Method of α-Particles Based on Radioluminescence

Abstract

The detection of α particles is of great significance in military and civil nuclear facility management. At present, the contact method is mainly used to detect α particles, but its shortcomings limit the broad application of this method. In recent years, preliminary research on noncontact α-particle detection methods has been carried out. In this paper, the theory of noncontact α-particles detection methods is introduced and studied. We also review the direct detection and imaging methods of α particles based on the different wavelengths of fluorescence photons, and analyze the application and development of this method, providing an important reference for researchers to carry out related work.

Research on the Technological Progress of CZT Array Detectors

“…In the detection of special nuclear materials, non-contact detection methods are used to detect radioactive isotopes using X-rays, and γ-passive non-destructive analysis characterized by X-ray spectroscopy is the preferred method [164]. High-purity germanium (HPGe) detectors have traditionally been the first choice for such applications.…”
