An Angular Response Controller for Radiation Measuring Instruments

Abstract

The invention provides an angle response controller for a radiation measuring instrument, and is used for angle response characteristic study and calibration / verification of detector positioning and angle adjustment of the radiation measuring instrument. A box body is fixedly connected with a base; a hand wheel is fixedly connected with a driving motor; the driving motor is fixedly connected with a worm active rotating shaft; an active worm gear is fixedly arranged in the center place of the worm active rotating shaft; a working table is arranged on the box body; a box cover disc is arranged between the box body and the working table; and a data transmission plug-in is externally connected with a 7SC 401 monaxial movement controller. The angle response controller can accurately position a radiation detector reference point to a radiation field checking point, and carries out angle adjustment, thereby reducing distance error and reading error, improving work efficiency, and reducing residence time of work personnel in a radiation field and occupation radiation dose.

Description

technical field [0001] The invention belongs to the field of ionizing radiation, and in particular relates to an angular response controller for a radiation measuring instrument, which can be used for the research on the angular response characteristics of the radiation measuring instrument, and the detector positioning and angle adjustment of the calibration / verification radiation measuring instrument. Background technique [0002] The response of radiation measuring instruments generally varies with the angle of the incident radiation to the detector reference direction. The response of the radiation measuring instrument at various angles and the response of the reference orientation when the radiation incident direction is consistent with the detector reference direction are compared, wherein the change of the radiation measuring instrument with the incident angle of radiation is called the angular response. In the development, finalization and use of radiation measuring ...

Problems solved by technology

At present, in the radiation measurement or radiation protection work, there is no device for accurate positioning and angle adjustment of the detector for the research of the angular response of radiation measuring instruments. During the adjustment process, it is difficult to ensure that the rotation axis passes through the detector reference point and the radiation field inspection point at the same time, so that the detector reference point will be displaced laterally relative to the radiation field inspection point. alignment and positioning of inspection points

For the angular response of radiation measurement, there are currently the following problems: angle adjustment, low accuracy of measurement results, affecting the accuracy of angular response research results; increased staff stay time in radiation control areas, occupational exposure dose; work efficiency is low Low
