Problems solved by technology

[0004] Although the X and γ dose rate meters of CZT semiconductor detectors are ideal dose detection equipment, there is no such detection equipment based on CZT semiconductor detectors in the domestic market. One of the major technical difficulties is how to design A high-sensitivity, wide-range and small-volume CZT semiconductor detector counting module

Abstract

The invention relates to a portable radiation dosimeter and dosage monitoring equipment, and belongs to the technical field of radioactivity detection instruments. The portable radiation dosimeter comprises a CZT (chemoreceptor trigger zone) detector, a signal processing system and a shielding case. The CZT detector is coupled with the signal processing system, the CZT detector and the signal processing system are both arranged in the shielding case, the signal processing system is used for conducting amplification, forming and screening treatment and outputting the electric signal output by the CZT detector, and the shielding case is made from a metal material. The outstanding detection efficiency is ensured by adopting the CZT detector. In addition, the signal processing system is adopted to conduct amplification, forming and screening treatment on the electric signal output by the CZT detector, accordingly the amplitude, pulse width and the like of the output signal can be changed,so that the dosage linearity of the portable radiation dosimeter and the dosage monitoring equipment is improved. The shielding case can protect the CZT detector and the signal processing system frombeing disturbed by outside electromagnetic signals, and thus the accuracy of the radiation dose rate can be improved.

Description

technical field [0001] The invention belongs to the technical field of radiation detection instruments, and in particular relates to a portable radiation dosimeter and dose monitoring equipment. Background technique [0002] While people are using nuclear energy and nuclear technology extensively, they are also facing special problems such as personal safety and environmental safety. Therefore, in order to ensure the safety of the public and the surrounding ecological environment in the application of nuclear technology, an environmental-grade dose rate meter is required to monitor the surrounding environmental radiation dose in real time. [0003] The probe parts of the main dosimeters currently on the market are mainly GM tubes and silicon diodes. Due to the large dead time of the GM tubes and the low detection efficiency of gamma rays, the angular response of the silicon diodes is poor and its response to gamma rays is poor. The low detection efficiency of gamma rays and...
