Problems solved by technology

However, when multiple neutrons in the pulse radiation field are simultaneously incident on the probe in a very short time, the pulse counting amplifier circuit cannot independently distinguish the pulse signals of multiple neutrons, resulting in the inability to accurately record the number of current pulse signals, and leakage occurs. The counting situation makes the neutron dosimeter unable to accurately detect the current neutron radiation dose value, thereby reducing the detection accuracy of the neutron dosimeter

Abstract

The invention provides a neutron dosimeter based on a current integration type electronics system, and belongs to the technical field of radiation dose detection. The neutron dosimeter comprises a probe module and a circuit module. Wherein the probe module comprises an outer-layer moderator, a metal layer, a polymer layer, an inner-layer moderator and a counter which are sequentially arranged from outside to inside, and neutrons can generate nuclear reaction in the counter to generate current signals. The circuit module comprises a signal amplification circuit and a data processing circuit, the signal amplification circuit can convert the current signal into a voltage signal, and the data processing circuit can convert the voltage signal into the current signal and can determine the radiation dose value of neutrons according to the current signal. In the detection process, the current neutron radiation dose value can be determined by acquiring the total charge quantity generated by the current neutrons without recording the number of the current pulse signals. Therefore, missed counting is avoided, and the detection precision of the neutron dosimeter is improved.

Description

technical field [0001] The present disclosure relates to the technical field of radiation dose detection, in particular to a neutron dosimeter based on a current integrating electronic system. Background technique [0002] The neutron dosimeter is a common tool to detect the neutron radiation dose value in the radioactive workplace. The dosimeter generally uses an electronic system based on a pulse counting amplifier circuit. However, when multiple neutrons in the pulsed radiation field are incident into the probe at the same time in a very short time, the pulse counting amplifier circuit cannot independently distinguish the pulse signals of multiple neutrons, resulting in the inability to accurately record the number of current pulse signals, and leakage occurs. The counting situation makes the neutron dosimeter unable to accurately detect the current neutron radiation dose value, thereby reducing the detection accuracy of the neutron dosimeter. [0003] The above informat...
