A dose rate detector and dose rate detection method

Abstract

The embodiment of the invention discloses a dose rate detector and a dose rate detection method, which relate to the technical field of radiation monitoring, and can avoid the detection method in which a person carries an instrument close to or enters a radiation area or a suspected radiation area in a traditional measurement method. The dose rate detection instrument of the present invention comprises: the first GM tube, the second GM tube, a positioning module, a wireless transmission module and an ARM processor; the positioning module is used to obtain the current position information of the dose rate detector, and send the position information to ARM processor transmission; the first GM tube and / or the second GM tube are used to obtain the dose rate monitoring information in the current environment of the dose rate detector, and transmit the dose rate monitoring information to the ARM processor; the ARM processor uses It is used to generate data packets containing location information and dose rate monitoring information; the wireless transmission module is used to transmit data packets outward. The invention is suitable for remote detection of radiation dose rate.

Description

technical field [0001] The invention relates to the technical field of radiation monitoring, in particular to a dose rate detector and a dose rate detection method. Background technique [0002] With the development of nuclear technology in the military and civilian fields, the requirements for nuclear energy safety are increasing. Radiation monitoring technology is widely used in nuclear industry production safety assurance, production accident prevention, and disaster rescue and treatment, so as to monitor the radioactive intensity in the environment in real time and ensure the safety of staff and emergency personnel. Among them, it is especially necessary to conduct fixed-point continuous monitoring of the dose rate of gamma radiation and determine the radiation safety area. [0003] GM tube is a component that can effectively monitor gamma radiation. It has the characteristics of large gas magnification, high output pulse amplitude, and output amplitude independent of i...

AI Technical Summary

Problems solved by technology

[0004] Although the GM tube has many of the above advantages, the GM tube also has problems such as small detection range and unintuitive measurement data. Therefore, when using an instrument equipped with a GM tube, it is often necessary for personnel with nuclear technology knowledge to approach or even enter the radiation area or It is a suspected radiation area for detection, which increases the operating risk of personnel, and the production safety of personnel cannot be effectively guaranteed
