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 ...

AI Technical Summary

Problems solved by technology

[0003] However, the arrangement of the existing radioactive sources is mainly carried out by manual experience, especially when the old and new sources are replaced, they need to be rearranged to ensure the uniformity of the radiation field.

[0004] Through the above analysis, the problems and defects of the existing technology are: the arrangement method of the existing radioactive sources takes a long time, and the arrangement result is not necessarily the optimal result, and at the same time, the efficiency is low
