Embodiment

[0022] Such as figure 1 As shown, the safety monitor disclosed by the present invention mainly includes a data processing module, a detector, a power supply module, a GPS positioning module and a communication module. Among them, the detector is used for real-time monitoring of radiation sources that may exist in the environment, and transmits the detection results to the data processing module. The GPS positioning module performs real-time positioning on the radiation source detected by the detector, and sends the positioning information to the data processing module. The data processing module performs data processing, analysis, and judgment on whether the detection result of the detector reaches the alarm threshold. Once the alarm threshold is reached, it communicates with the external data center or mobile terminal through the communication module to send an alarm signal. The power supply module provides power for other devices, and charges other devices during the sleep ...

Abstract

The invention discloses a safety monitor for gamma and neutron radiation in the environment. The safety motor comprises a CPU, as well as a detector module, a data communication module, a power supply module and a GPS module which are connected with the CPU, wherein a time counting circuit is arranged inside the detector module which is additionally provided with a neutron / photon conversion structure; the data communication module is wirelessly connected with an external mobile phone mobile terminal or a data management center; the power supply module is connected with the detector module and the GPS module respectively, and a charging and discharging circuit and a high-voltage boosting circuit are arranged inside the power supply module. According to the safety monitor for the gamma and neutron radiation in the environment, various sources of radiation can be detected by one monitor, a warning signal is sent in real time, the size of the monitor is reduced effectively, a foundation is laid for the wide popularization and application, and the practical value of the monitor is improved.

Description

technical field [0001] The invention relates to a monitor, in particular to an environmental gamma and neutron radiation safety monitor. Background technique [0002] On May 9, 2014, the loss of iridium-192 occurred in Nanjing, China, which caused panic among Nanjing citizens and the close attention of the local government. After the nuclear accident, the iridium-192, which belongs to the second class radioactive source with an activity of 25 curies, has been picked up and discarded by many people, and its position has changed greatly. [0003] The popularity of nuclear applications, radioactive sources and radioactive waste are increasing. If these dangerous substances are carried by terrorists and left in densely populated areas, it will cause very serious social security consequences. How to quickly locate radioactive sources and provide early warnings to surrounding people has become an important part of environmental monitoring. [0004] In order to realize the detec...
