Description

Technical Field

[0001] The invention relates to the technical field of radiation testing in ionizing radiation sites, and in particular to a rotating platform for ionizing radiation testing. Background Art

[0002] In ionizing radiation testing, the radiation dose rate at a certain location is inversely proportional to the square of the distance from the radiation source. The greater the distance from the radiation source, the smaller the dose rate at that location. In actual testing, in order to adjust the distance of the object under test, it is necessary to adjust the distance of the object under test through a lateral moving mechanism. However, it is difficult and costly to fine-tune the test distance through a lateral moving mechanism. At the same time, in order to save testing costs, the pitch angle of the object under test can be fine-tuned to achieve a slightly variable position difference between the surface of the same object under test and the transmitting device, so as to measure the difference in radiation dose rate at a short distance. Therefore, it is necessary to design a device that can change the angle of the object under test. Summary of the invention
