Gamma energy disperse spectroscopy

Abstract

The invention provides a gamma energy disperse spectroscopy, which comprises a detection end and a remote monitoring end. The detection end comprises a detection module used for converting gamma raysinto electric signals; a signal processing module used for shaping and amplifying the electric signals outputted by a detector array; a data acquisition and analysis module used for carrying out sampling and analyzing electric pulse signals after being subjected to shaping and amplifying treatment; a temperature detection module used for acquiring the temperature of the working environment; an alarm module used for giving an acousto-optic alarm; a wireless communication module used for realizing data transmission between the detection end and the remote monitoring end; and a microprocessor used for giving an alarm when the temperature exceeds a threshold value. The data acquisition and analysis module, the signal processing module and the wireless communication module are controlled to carry out data processing and data transmission. The remote monitoring end comprises a visual interface and a data processing software. The data processing software comprises a nuclide identification module used for recognizing nuclides, and a radon gas content measuring module used for measuring the content of radon gas.

Description

technical field [0001] The invention relates to the field of energy spectrum detection of gamma rays, in particular to a gamma energy spectrometer. Background technique [0002] Gamma spectrometers are widely used in radioactive monitoring of geological industry, food, sanitary environment, production and testing of building materials, construction industry and other fields. In these applications, many of them work in the field, and the instrument functions are required to meet the technical requirements, and at the same time, it needs to have the advantages of convenient operation, low power consumption, and portable structure. There are two main types of existing gamma spectrometers: one is the gamma spectrometer constructed with the existing computer as the data processing center, and this type of gamma spectrometer has strong data processing and real-time display The ability of the line, the measurement terminal and the computer mainly use the serial port or USB communi...

Problems solved by technology

There are two main types of existing gamma spectrometers: one is the gamma spectrometer constructed with the existing computer as the data processing center, and this type of gamma spectrometer has strong data processing and real-time display The ability of the cable, the measurement terminal and the computer mainly use the serial port or USB communication method, these two communication methods must have a cable for physical connection, it is inconvenient to operate in the field, the cable is prone to faults such as poor contact and short circuit The power consumption of the whole machine is large, the volume is large, it is difficult to integrate into a special instrument, and it is not suitable for field measurement

The other type is a gamma spectrometer built with a single-chip microcomputer. At present, the latest gamma spectrometer of this type is integrated with a liquid crystal and a keyboard, which is easy to operate and has basic functions such as data collection, display, and storage, but the data processing capacity is not enough. Strong, not suitable for large-scale data calculations, and unable to meet the needs of on-site technicians. At the same time, this type of gamma spectrometer adds LCD and keyboard modules to traditional gamma spectrometers, which also increases the size and function of the instrument. consumption
