Problems solved by technology

Counting tubes, gas ionization chambers, and photomultipliers have high power supply requirements. It is difficult for ordinary smart devices to meet their power supply requirements, and they are large in size. Solid-state detectors usually need to detect in a low-temperature environment, so they cannot meet the detection under general working conditions. Require

Abstract

The invention provides a radiation dose monitoring system and detection method. The technical key points of the system are that the system comprises a radiation dose detector and intelligent portable communication equipment. The radiation dose detector is provided with an MPPC module which is connected with a microprocessor. The radiation dose detector is connected with the intelligent portable communication equipment through a Micro USB interface. The method comprises the steps that a radiation signal is detected by the MPPC module and the signal is transmitted to the microprocessor in the form of an electric signal, data processing is performed by the microprocessor and whether the dose exceeds the standard is judged, and the detection value is only displayed by an LED display screen is the judgment result is no; and if the judgment result is yes, the detection data are displayed by the LED display screen and a work indicating lamp is started for warning and alarming to the intelligent portable communication equipment is performed. The radiation signal of the radioactive source is received through the MPPC module and the received radiation signal is processed and then transmitted to the microprocessor in the form of the electric signal, and whether the dose exceeds the standard is judged by the microprocessor so as to judge leakage of the radioactive source.

Description

Technical field: [0001] The invention relates to the field of radiation dose supervision, in particular to a radiation dose monitoring system and detection method. Background technique: [0002] With the rapid development of the national economy, the application of radioactive sources and radiation devices is becoming more and more extensive, which plays an important role in promoting the development of the national economy and improving the quality of life of the people. However, since radioactive sources are colorless, odorless and invisible, they are more dangerous than "nuclear killers". Through the investigation and summary of the causes of the accident, it can be attributed to two reasons: one is that the safety supervision of radioactive sources is not in place due to the lack of law enforcement personnel and heavy law enforcement tasks; the other is that the means of radiation environment supervision and the law enforcement process are not perfect. In terms of radio...
