Security And Inspection Systems Of Radioactive Sources Based On RFID

In recent years, the radioactive sources and apparatus are widely used in China with the development of nuclear technology. However radioactive accidents would happen when radioactive sources were lost, stolen or transferred illegally. It will not only make the environment contaminated by radiation, and cause injury to persons, can also cause social panic and affect social stability.In this paper, we first introduced the present status of management and security technology of radioactive sources. Then the feasibility of RFID technology in the security systems of radioactive sources was analyzed. The paper also described the security and inspection system of radioactive sources based on RFID technology. The details of the security and inspection system were demonstrated including of the designs of the equipments in this system. This paper designed to achieve the functions of anti-theft alarm and inspection in the radioactive sources system. On this basis we proposed the design of the radioactive sources storage system.Hardwares including radioactive sources electronic tags, readers, the annunciator alarm were designed and developed for the radioactive sources system. The whole system provided the security monitoring of radioactive sources. The slave reader was an effective solution to the problem of monitoring radioactive sources in wide range. The unique design in the electronic tags solved the problem about radioactive sources tracking. It will generate an alarm signal when the electronic tags were detached from the radioactive sources.In this paper, a radioactive sources handset was developed to achieve the inspection function of radioactive sources. And the scheme of the radioactive sources storage system was put forward using this handset. We did preliminary study on the radioactive sources storage system. This handset was a combination of MTK mobile phone module and MCU system, which can greatly reduce the time of the development process and effectively reducing the total cost. This handset was stable, reliable and easy to use.
