Abstract

The invention belongs to the technical field of radioactive sources, and discloses a radioactive source arrangement method and system, and the system comprises: a parameter obtaining module and a radioactive source energy obtaining module which are respectively used for obtaining the arrangement parameters of a radioactive source and the energy of the radioactive source; a radioactive source activity measurement module, an irradiation dose rate determination module, an irradiation dose calculation module, a to-be-radiated article absorption dose calculation module and a total irradiation dosecalculation module which are respectively used for determining the radioactive source activity, the irradiation dose rate of a radioactive source, the irradiation dose rate of the radioactive source at a reference point, the to-be-radiated article absorption dose and the total irradiation dose; an arrangement position calculation module and an evaluation module which are respectively used for determining the arrangement position of the radioactive source and evaluating the result; and an arrangement module which is used for arranging the radioactive sources. According to the invention, a plurality of radioactive source arrangement modes can be provided, and quantitative evaluation is carried out on each arrangement mode, so that the optimal arrangement method is determined, and the radioactive source arrangement mode with the minimum reference surface dose rate non-uniformity is obtained.

Description

technical field [0001] The invention belongs to the technical field of radioactive sources, and in particular relates to a method and system for arranging radioactive sources. Background technique [0002] At present, radioactive source is a general term for radiation sources made of radioactive materials. The radioactive source is generally marked by the activity of the radionuclide produced, and its strength can also be marked by the ray emissivity or fluence rate. It is customary to refer to radiation sources with high activity or high radiation emission rate used in non-destructive testing, radiation therapy, and radiation treatment as radiation sources. Radiation application technology based on radioactive sources is widely used in industry, agriculture, medicine, resources, environment, military, scientific research and other fields. [0003] However, the arrangement of the existing radioactive sources is mainly carried out through manual experience, especially when ...
