Abstract

The invention belongs to the technical field of radioactive detection instruments, and specifically provides a portable gamma spectroradiometer. The portable gamma spectroradiometer comprises a power supply system (4), a detector system (5) and a signal processing system (6), wherein the detector system (5) comprises two single-layer CZT detectors (1) which are laminated together up and down; the electric signals of the two single-layer CZT detectors (1) are connected into the signal processing system (6) after being connected in parallel; the power supply system (4) is connected with the detector system (5) and is used for supplying power for a laminated CZT detector consisting of the two single-layer CZT detectors (1). The portable gamma spectroradiometer overcomes the problems that the efficiency of a single detector is not high and the precision of a final dosage value is not high caused by the fact that a portable gamma spectroradiometer in the prior art uses the single CZT detector in a single energy spectrum analysis manner.

Description

technical field

[0001] The invention belongs to the technical field of radiation detection instruments, and in particular relates to a portable gamma radiation spectrometer. Background technique

[0002] Restricted by factors such as industry development and foreign nuclear-related technology restrictions, domestic spectrometer technology has not developed significantly in the past 20 years, and there is a big gap with foreign countries. So far, there is no mature digital multi-channel spectrometer or portable spectrometer that is widely accepted by the market. Gamma dosimeter products launched.

[0003] In recent years, various foreign spectrometer manufacturers have launched a variety of digital portable spectrometers based on CZT detectors, mainly including the Interceptor spectral personal radiation detection system jointly launched by Thermo Company and Target Instrument Company, microRaider developed by ICX Company, Lawrence A pocket spectrometer developed by Berkeley...
