Portable X-ray flaw detector radiation dose control unit

Abstract

The invention discloses a portable X-ray flaw detector radiation dose control unit and solves the problem that radiation injury of detectors caused by the prior art cannot be avoided. The portable X-ray flaw detector radiation dose control unit comprises an individual wearing-type X-ray dose monitor controller (A), an X-ray power controller (B), an X-ray generator operating cabinet (C) and an X-ray generator (D). The individual wearing-type X-ray dose monitor controller (A) is provided with a radiation detector (5) and a dose monitoring single-chip microcomputer (4) inside. A battery (8) is connected with an input end of a direct-current booster (6) through a dose monitoring power switch (3). An output end of the direct-current booster (6) is connected with a power end of the radiator detector (5). A pulse signal output end of the radiation detector (5) is connected with the dose monitoring single-chip microcomputer (4). The dose monitoring single-chip microcomputer (4) is connected with a wireless communication transmitter card (2). Autonomous protection based on radiation dose control is realized for detectors for the portable X-ray flaw detectors.

Description

technical field [0001] The invention relates to a radiation dose control device for a portable X-ray flaw detector, which is used for automatic protection of inspectors based on personal radiation dose control in the process of X-ray non-destructive flaw detection. Background technique [0002] In non-destructive testing, since X-ray testing methods can directly obtain intuitive images of internal defects of components, and can accurately judge the nature, quantity, size and location of defects by observing the film, it is widely used in the manufacturing inspection of special equipment such as boilers and pressure vessels. It is widely used in service inspection. However, X-rays will cause harm to the inspectors, and protective measures need to be taken, that is, to control the radiation exposure to the human body to keep it at a reasonable minimum level, so as to ensure that the radiation equivalent dose received by individuals does not exceed the prescribed standard.
