多能点γ准直标定源的建立及其应用

Building and application of a collimated γ-ray source with multi-energy point

介绍了利用工业60Co线状源建立多能点γ准直标定源的方法。阐述了理论依据、大幅度降低散射本底的措施、理论计算方法、注量率实测方法、对安全防护和承重问题的考虑等,并对实验结果进行了讨论。

The paper introduces a method to build up a collimated multi-energy point T-ray source for experiment with an industrial 60Co source. In details the theoretical design, measurement method of reducing scattered background greatly and measurement of flux, theoretical computation method, solution for radioprotection and weight bearing problem, and so on have been described and discussed. The experimental results show that the building of new method has better application.
