Abstract

The invention relates to a radiation detection device and a chip, through a radiation detection circuit configured with a gamma ray detection probe and a neutron detection probe, detection of gamma rays or neutrons is completed at the same time, and detection of various particles is realized. Meanwhile, when the dose rate is smaller than or equal to a dose limit value, a detection signal of the radiation detection circuit is obtained through a pulse mode circuit, the output pulse number is the same as the particle number corresponding to the detection signal, and an external processor calculates to obtain a detection result; and when the dose rate is greater than the dose limit value and exceeds the upper limit of the counting rate of the pulse mode circuit, the current mode circuit is adopted to convert the measured current into voltage, and the detection result is calculated through an external processor. On the basis, through cooperative work of a pulse reading mode and a current reading mode, wide-range detection of radiation detection is realized.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a radiation detection device and a chip. Background technique [0002] Radiation detection is a technical means of observing microscopic phenomena of specific objects through radiation detectors. Among them, the radiation detector is the core equipment of radiation detection. It mainly uses the principle of the interaction between particles and matter to characterize the microscopic phenomena of nuclear radiation and particles as observable macroscopic phenomena. Traditional radiation detectors mainly include gas ionization detectors, semiconductor detectors and scintillation detectors. [0003] Due to the complex application scenarios of radiation detection, there may be many different types of particles, and the characteristics of different particles vary greatly. Therefore, traditional radiation detectors cannot fully satisfy the detection of various particles in...
