A real-time surveillance and management system for mobile radiation sources

This paper presents results of a real-time surveillance and management system for security of radioactive material (BKRAD). The BKRAD integrates various positioning and sensing techniques that allows us to continuously monitoring radiation source devices in a variety of challenging environmental conditions, such as indoor or underground areas. The unique aspect of the BKRAD is its ability to identify and recover radiation source projectors that were stolen or lost using specialized equipment that is secretly attached to each projector. In addition, this product is equipped with a hightech sensor system to improve the safety and security of radiation sources against unauthorized access. 1 Introduction: Radiation and nuclear technologies have been deployed rapidly and broadly in various industrial and economic sectors and society, which has brought various practical benefits. However, the management, transportation, storage and usage of radiation sources, such as nondestructive testing (NDT) devices, are complicated by many challenges. In fact, there have been many losses of radiation sources resulting in significant impacts on economic and social stability. Although these incidents did not cause serious radiological impacts on human and environment, but they have made a big public concern on physical protection of radioactive and nuclear materials. Therefore, a system for security of radioactive material in NDT devices is very necessary. In this project, we have successfully designed, manufactured and tested the BKRAD for security of radioactive source in Vietnam.
