AI Technical Summary

Technical Problem

Existing radionuclide production systems face challenges in efficiently removing heat load from target material plates during particle beam irradiation, leading to contamination by impurities and increased purification costs due to the use of raw materials with low thermal conductivity and formability, which restricts equipment design and selection.

Method used

A radionuclide production system utilizing a target cooling plate made of silicon dioxide or an oxide film on the target cooling plate to improve cooling performance and prevent contamination, where the target material is mounted on this plate to generate radionuclides efficiently while suppressing impurity mixing.

Benefits of technology

The system effectively cools the target material, reducing contamination and purification costs, enabling flexible equipment design and ensuring the quality and safety of produced radionuclides.

Abstract

To provide a radioactive nuclide production system and a radioactive nuclide production method which improve cooling performance of a target material including a material nuclide, suppress contamination of impurities to the target material, and are capable of efficiently producing a radioactive nuclide.SOLUTION: A radioactive nuclide production system 1 comprises: a particle beam irradiation device 10 which generates a particle beam 11; and a target 20 which generates radioactive nuclide by irradiation of the particle beam 11. In the target 20, a target material 21 including a material nuclide generating the radioactive nuclide is mounted on a target cooling plate 22 cooling the target material 21. In a radioactive nuclide production method, the target material 21 including the material nuclide forms the target 20 mounted on the target cooling plate 22 cooling the target material 21, and the target 20 is irradiated with the particle beam 11 or bremsstrahlung while cooling the target material 21 by the target cooling plate 22 to produce radioactive nuclide.SELECTED DRAWING: Figure 1
