Enhancing the capability of the physical protection system for radioactive sources with intelligent radiation detectors

Abstract

For the use of radioactive materials, adequate physical and radiation protection must be established in accordance with the actual regulations. This article investigates whether radiation detectors, which are mandatory in radiation protection, can be used as an electronic sensor to alert the physical protection system in case of a robbery. An intelligent radiation detector can sense the presence of a radiation source, thus also being able to indicate if someone is trying to move (steal) the radiation source. This article describes the basics of an algorithm by which an intelligent detector can become suitable as an electronic device for generating signals for physical protection systems while retaining the original radiation protection purpose of the detector. I verify the operation of the system through measurements and examine the possibilities for further development. The developed procedure can improve the protection of radiation sources, make their use safer, without the need to build additional equipment.
