Gamma dose monitoring device based on remote wireless communication

Abstract

The invention discloses a gamma dose monitoring device based on remote wireless communication. A silicon photodiode detector based on a 4G wireless communication module and provided with a scintillator is used. The monitoring device is combined with upper computer software so that the radiation doses at multiple places can be remotely measured, and data can be processed and stored. According to the device, the small-size silicon photodiode detector with the scintillator is used, the gamma particle radiation detection efficiency is high, the time resolution and the space resolution are very good, and due to the efficient detection efficiency and the high anti-interference capability of the device, an environment-level gamma background can be detected. The device also has an energy spectrumanalysis function and can be used for element analysis. The whole set of measurement system carries out calibration experiments through standard Eu-152 and Cs-137 gamma radioactive sources, the measurement result is stable, and the conformity of measurement data is high compared with a professional handheld dose instrument. The device can be applied to nuclear environment monitoring of standard nuclear facility places and can also be applied to numerous fields of nuclear emergency and the like.

Description

technical field [0001] The invention relates to the technical field of gamma ray dose monitoring and 4G Internet of Things transmission, in particular to the application occasions of radiation environment monitoring such as random weak pulse signal acquisition and processing of gamma ray, and remote big data transmission. Background technique [0002] Gamma ray, also known as γ particle flow, is the ray released when the nuclear energy level transition de-excites, and is an electromagnetic wave with a wavelength shorter than 0.01 Angstroms. Gamma rays have strong penetrating power, and can be used for flaw detection or automatic control of assembly lines in industry. Gamma rays are lethal to cells and are used medically to treat tumors. The γ-ray is incident on the crystal, and the photoelectric effect, Compton effect and electron pair effect occur. These secondary electrons move in the crystal, consume energy in the crystal, ionize and excite the atoms in the crystal, and...
