Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] figure 1 The principle of the preferred embodiment of the multi-dimensional detection device of the whole-body radioactive surface contamination monitoring system of the present invention is shown. See figure 1 The multi-dimensional detection device of this embodiment includes a detection control chip 1 (in this embodiment, a C8051F020 single-chip microcomputer 1) as the core of control and detection, multiple sets of moving devices, an arc surface rotation mechanism for a planar radiation source, and a manual reversing mechanism 7 . The single-chip microcomputer 1 completes the movement control, position detection, coordinate calculation and display of the whole device. In this embodiment, the multiple groups of moving devices are respectively: the drive control detection circuit 20 on the X coordinate and its matching stepping motor 21 (as t...

Abstract

The invention discloses a multidimensional detection device of a whole body radioactive surface contamination monitoring system. Radioactive sources are placed in front of a measuring terminal of each detector by the multidimensional detection device in stead of manual work, each detector is detected to determine detection efficiency and flexibility of the same, the whole process can be automatically completed with a small amount of manual intervention, and the defects of a manual operation method and potential harm are solved. The technical scheme includes that multidimensional space positioning and movement of alpha, beta and gamma plane sources is realized, the detection and correction problems of the whole body radioactive surface contamination monitoring system are solved and detection is automated due to the fact that the control technology taking a single-chip microcomputer as a core is adopted, ball screw nut machinery is taken as an actuator and a stepping motor is utilized to drive the actuator, the ball screw nut machinery.

Description

technical field [0001] The invention relates to a detection device for radioactive contamination, in particular to a multi-dimensional detection device for a whole-body radioactive surface contamination monitoring system. Background technique [0002] With the construction of nuclear power plants, there are more and more people working in nuclear power plants. The staff in the radiation control area may be exposed to radiation and contaminated with radioactive substances. Radiation and contamination with radioactive substances, through the detectors on the whole body radioactive surface contamination monitoring system, the radioactive surface contamination can be detected in time, and corresponding measures can be taken to eliminate the danger. The normal operation of this equipment plays an important role in ensuring the personal safety of nuclear power plant workers. [0003] The whole body radioactive surface contamination monitoring system is a multi-dimensional space, ...
