Problems solved by technology

The existing method is to use conventional radiation detection instruments to be placed at set points, and to complete the detection point by point. During the detection, it is necessary to repeatedly enter and exit the computer room, and it is inconvenient to place detection instruments on predetermined detection points, requiring a lot of configuration. bracket to complete
If the accelerator leaks a lot, it is likely to exceed the range of conventional radiation detection instruments. If you don’t know it in advance, you will not only be unable to measure accurately, but will also damage the detection instrument.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0016] refer to figure 1 , figure 2 , the accelerator head leakage radiation test method, determine 24 detection points on the accelerator head, each detection point is placed with a thermoluminescence dosimeter, and each thermoluminescence dosimeter simultaneously detects the leakage radiation of the detection point, After the test, the thermoluminescent dosimeter is removed for data reading. The thermoluminescence dosimeter used in the present invention is low in cost, can be conveniently placed on the detection point, and can detect all the required points at one time, greatly improving the detection efficiency, and can ensure t...

Abstract

The invention provides a method for testing radiation leakage from an accelerator head. 24 detection points are determined on the accelerator head, and a thermoluminescence dosimeter is placed at each detection point. Carry out leakage radiation detection, and remove the thermoluminescence dosimeter for data reading after the detection. The thermoluminescent dosimeter used in the present invention has low cost, can be conveniently placed on the detection point, and can detect all the required points at one time, greatly improving the detection efficiency, and can ensure the accuracy of the detection point position, and can also reduce the Risk of instrument damage.

Description

technical field [0001] The invention relates to a method for testing radiation leakage of an accelerator head. Background technique [0002] Radiation leakage from the accelerator head is a necessary inspection item of the accelerator inspection project. It is necessary to complete the radiation inspection of 24 points on the spherical surface 1m away from the focal point when the accelerator is turned on. The existing method is to use conventional radiation detection instruments to be placed at set points, and to complete the detection point by point. During the detection, it is necessary to repeatedly enter and exit the computer room, and it is inconvenient to place detection instruments on predetermined detection points, requiring a lot of configuration. bracket to complete. If the accelerator has a large leakage, it is likely to exceed the range of conventional radiation detection equipment. If it is not known in advance, it will not only fail to measure accurately, but...
