A radiation detection device

Abstract

The invention provides a radiation detecting device. The device comprises a detector shell, a detector, a main plate and a handle. The detector comprises a scintillation crystal and a photoelectric conversion device which are coupled to each other. The main plate and the photoelectric conversion device are connected in a communication connection mode, the main plate and the detector are arranged in the detector shell, the handle and the detector shell are connected and a battery chamber is arranged in the handle, a battery is placed in the battery chamber, and the battery is electrically connected to the main plate. The handle is provided with a battery chamber cover which is cooperated with the battery chamber, a sleeve is arranged outside the handle, and the battery chamber cover is located in the sleeve and abuts against the inner wall of the sleeve. The device comprises an adjusting mechanism and a protection cover. In the invention, multiple insurances are provided to solve a problem that the battery and the battery chamber cover are easy to fall off, and disassembly is convenient; a detection range is wide, a detection effect is better, and the protection cover is not easy tolose.

Description

technical field [0001] The present invention relates to the technical field of radiation detection, and more particularly to a radiation detection device for detecting alpha rays and beta rays. Background technique [0002] Ionizing radiation refers to the general term for all radiation that can cause ionization of matter, including alpha rays, beta rays, gamma rays, X rays, neutron rays, etc. Ionizing radiation is divided into direct ionizing radiation and indirect ionizing radiation. Among them, α-rays, β-rays, protons, etc. are charged and can directly cause ionization of matter; When acting, "secondary particles" are generated to ionize the material. With the development of nuclear technology, the application of ionizing radiation in daily life is becoming more and more common, such as alpha and beta radioactive pollution on surfaces such as workplaces, laboratories, hospitals, isotope production plants, work surfaces, floors, walls, hands, clothes, etc. . However, be...

Problems solved by technology

In the prior art, there are two common design schemes for fixing the battery compartment cover at present: the first one adopts the structure of the battery compartment cover fixed by screws, and the disadvantage of this method is that tools are needed when replacing the battery; the second one is fixed by buckles The structure of the battery compartment cover is fixed with buckles instead of screws. The disadvantage of this method is that the battery compartment cover and battery will fall off and be lost when the device is accidentally dropped, which poses hidden dangers in use.
