Method and system for automatically monitoring and real time monitoring radioactive source

Abstract

The invention relates to a radioactive source automatic supervision and real-time monitoring method and a system. The method mainly comprises the following steps: a positioning terminal in which a GPS positioning unit and a CDMA network positioning unit are arranged and source file information is solidified is arranged on a radioactive source; the source file information is stored in a network server of a monitoring center and a source admission range is set up; source position information and source file information is acquired at real time and corresponding source information in the network serve is updated at real time; when the source information stored in the network server changes, the monitoring center automatically obtains prompting information and judges whether the change of the source information is beyond the admission range; when the change of the source information exceeds the admission range, automatic alarm is carried out. The system realizing the method comprises a positioning terminal assembly device, a source information storing device, a source information updating device, a source information monitoring device and a real-time alarm device. The method and the system realize automatic supervision and real-time monitoring of all links of the radioactive source, thereby putting an end to severe security accidents like loss of the radioactive source, etc.

Description

technical field [0001] The invention relates to the field of radioactive source management, in particular to a method for automatic supervision and real-time monitoring of radioactive sources in a source library, in fixed use, in mobile use, in transportation, and tracked after being lost, and a system for realizing the method. Background technique [0002] The application of radioactive sources in my country began in the 1950s. After years of unremitting efforts, radioactive sources have been widely used in the fields of national defense, medical care, energy, industry, agriculture, scientific research and other fields in our country. However, the safety issues in the application of radioactive sources are becoming more and more prominent. There are more than 50,000 radioactive sources in my country, and the users are involved in various industries. There are many and scattered units. Radioactive accidents caused by improper use or loss of radioactive sources continue to o...

Problems solved by technology

[0006] 2. Completely rely on the system to manage personnel to ensure the safety of radioactive sources, but the staff may be negligent. Once it happens, there will be no other technical measures to ensure that major accidents will occur

[0008] However, this kind of measure can only play the role of tracking and positioning after the radioactive source accident occurs, and cannot prevent and avoid the occurrence of accidents, and has limitations.
