Abstract
This paper proposes to design security measures based on the radioactive material package as the basic unit. The principle of four-layer defense in depth is put forward. Based on the concept of self-security intelligence, combined with out-of-vehicle monitoring, in-vehicle monitoring, and Beidou positioning technology, a security system for transport of radioactive materials was designed. It realized the perception, early warning, delay, and alarm functions and greatly improved the security.
Highlights
Since the transport security level is determined according to the package, we believe that it is necessary to decentralize security measures to the package, not just the conveyances of transportation
At the basic security level, the packaging container is equipped with electronic equipment to provide basic detection and alarm functions
It includes the self-security intelligence of individual radioactive material [13] and the swarm selfsecurity intelligence of radioactive materials [14]. e former uses sensors to detect the illegal approach of the intruder and takes measures to delay the intrusion, such as on-site alarm, evasion, or resistance. e swarm self-security intelligence shares the intrusion information detected by the device through the network and can identify the illegal movement of radioactive material through group relationships and respond . e connection between the intelligent electronic device and the radioactive material container needs to be strengthened
Summary
Radioactive material self-security intelligence means installing intelligent electronic device on the radioactive material container to achieve the functions of detection, delay, and response. It includes the self-security intelligence of individual radioactive material [13] and the swarm selfsecurity intelligence of radioactive materials [14]. E swarm self-security intelligence shares the intrusion information detected by the device through the network and can identify the illegal movement of radioactive material through group relationships (via the network) and respond . E connection between the intelligent electronic device and the radioactive material container needs to be strengthened. It should not be dropped due to vibration during transportation or easy removal by suspicious persons
