Measuring device for dose distribution of ray radiation field

Abstract

The invention relates to a radiation measuring device, and provides a measuring device for dose distribution of a ray radiation field. The measuring device aims to solve problems of existing measurement for distribution of radiation fields, improve the measurement precision and quantitatively measure an actual dose distribution condition of the radiation field. The measuring device comprises a bottom plate, a base, a balance plate and a plurality of thermoluminescent elements; each thermoluminescent element comprises an element cover plate, an element base and a thermoluminescent detector, and each thermoluminescent detector is arranged in clamp grooves of the corresponding element base; the thermoluminescent elements are uniformly arranged between the bottom plate and the balance plate which are parallelly placed, the bottom plate and the balance plate are fixed onto the base, and the bottom plate, the balance plate, the element cover plates and the element bases are made of organic glass. The measuring device for the dose distribution of the ray radiation field has the advantages that measurement errors can be reduced, the measurement precision can be improved, accurate information of the edge of the radiation field can be acquired, the integral radiation field can be measured by means of one-step radiation, the required time is quite short, and the measuring device is low in cost.

Description

technical field [0001] The invention relates to a radiation measuring device, in particular to a radiation field dose distribution measuring device. Background technique [0002] There are many aspects to the application of radiation, but it mainly uses the interaction between radiation and matter. In order to meet its use conditions, a specific radiation device must be provided. Especially in the fields of medical treatment, medical imaging diagnosis, industrial flaw detection imaging and metrology calibration. [0003] Irradiation installations containing radioactive sources, as well as irradiation installations consisting of particle accelerators or X-ray machines, generate radiation fields, sometimes referred to as irradiation fields. In the application of radiation, the performance of the radiation field ultimately determines the performance of the device. Generally, it is hoped to obtain a uniform radiation field, so the dose distribution of the radiation field must ...
