Radiation safety monitoring equipment detection system and design method thereof

Abstract

Disclosed is a radiation safety monitoring equipment detection system, including a front diaphragm system, a shutter system, a lead container, a rotor, a drive positioning system, a base, an excitation device, a radiation source, a door source, a monitoring system, a radiation source overall structure, a radiation safety monitoring equipment supporting platform system, an image acquisition and processing system, a data upload system and a safety interlock system. Also disclosed is a design method of the radiation safety monitoring equipment detection system. When a ray emitted by the radiation source passes through a diaphragm system, a part of the ray penetrates directly without changing energy or direction thereof, another part of the ray is absorbed by a wall of the diaphragm system, and the rest is scattered. The radiation safety monitoring equipment detection system and the design method thereof have the advantages of high accuracy and high stability, and provide technical basic conditions and crucial metering guarantees for magnitude unification of rays in the fields of radiation protection for radiation therapy, radiation working staff and the public, nuclear power, safe operation of nuclear facilities and the like to meet the social development needs.

Description

technical field [0001] The invention relates to the field of radiation safety monitoring equipment detection, in particular to a radiation safety monitoring equipment detection system and design method. Background technique [0002] During the use of radiation intensity detection equipment, the detection equipment needs to be calibrated regularly. The existing standard radiation source usually has a complex structure and a single radiation source intensity. The original source room is designed so that the radiation source is in close contact with the shielding material. No gaps beyond mechanical installation or motion requirements are intentionally left. In this state, the rays emitted by the active area of ​​the radioactive source are emitted together with the main beam after only one backscattering in many cases, which greatly increases the low-energy components in the beam. A basic requirement for a radiation beam as a measurement standard is that the energy spectrum of ...
