Abstract

Molybdenum-99 is one of the most important radionuclides for medical diagnostics. In 2015, the International Atomic Energy Agency organized a round-robin exercise where the participants measured and calculated specific saturation activities achievable for the Mo(n,γ)Mo reaction. This reaction is of interest as a means to locally, and on a small scale, produce Mo from natural molybdenum. The current paper summarises a set of experimental results and reviews the methodology for calculating the corresponding saturation activities. Activation by epithermal neutrons and also epithermal neutron self-shielding are found to be of high importance in this case.

摘要

钼-99是医学诊断中最重要的放射性核素之一。2015年，国际原子能机构组织了一次循环检验活动，参与者对通过钼(n,γ)钼反应可实现的比饱和活度进行了测量和计算。该反应作为一种从天然钼中局部小规模生产钼的手段备受关注。本文总结了一组实验结果，并回顾了计算相应饱和活度的方法。发现超热中子活化以及超热中子自屏蔽在这种情况下非常重要。
