Abstract

The invention discloses a personal dosimeter based on a SiPM and CsI detector. The personal dosimeter comprises a detector, a power supply and charging circuit, a bias voltage circuit, a signal amplification circuit, a signal discrimination circuit, a microprocessor and data storage man-machine interaction, wherein the detector comprises a SiPM probe and a CsI probe; the power supply and chargingcircuit is used for supplying power to the whole circuit, and the bias voltage circuit is used for providing a voltage battery and a charging circuit required by work for the SiPM probe; the signal amplification circuit is used for amplifying a signal generated by the SiPM probe to a proper amplitude; the signal discrimination circuit is used for filtering out unnecessary noise signals, and the filtered signals are sent to a counter of the microprocessor to be counted, so that the value of the radiation intensity is obtained. The personal dosimeter adopting the combination of SiPM and CsI as the detector can well solve the problems of low sensitivity and poor anti-interference capability of other existing personal dosimeters, and also solves the problems of large size and high power consumption.

Description

Technical field [0001] The invention relates to the technical field of detectors, in particular to a personal dosimeter based on SiPM and CsI detectors. Background technique [0002] The existing personal radiation dosimeter uses a Geiger counter, silicon photodiode or a combination of silicon photodiode and CsI as the sensor. [0003] The disadvantages of using a Geiger counter as a sensor personal dosimeter are low sensitivity, a high voltage of hundreds of volts required for the work of the Geiger counter, large size of the instrument, high power consumption, and most Geiger counters are extremely easy to break. [0004] The shortcomings of personal dosimeters using a single silicon photodiode as the sensor are that the sensitivity is very low, the photoelectric gain is low and it is easily interfered, and good shielding is required when designing. The use of a single silicon photodiode and a CsI combination as the detector improves the sensitivity to a certain extent, but due to...
