摘要

我们已经设计了一种密封点源的标准化方法，可以应用于像22Na这样发射正电子和至少一种伽马射线的核素。这种方法是基于一个闪烁探测器阵列对湮灭辐射和伽马射线的重合计数。在本研究中，我们进行了蒙特卡罗模拟，以检验该方法在各种测量条件下的性能。EGS5蒙特卡罗仿真结果验证了该方法对利用BGO闪烁探测器阵列测量22Na密封点源的有效性

Evaluation of a standardization method for 22Na sealed point sources for various measurement conditions

We have devised a standardization method for a sealed point source that can be applied to nuclides such as 22Na that emit a positron and at least one gamma ray. This method is based on coincidence counting of annihilation radiation and gamma rays using a scintillation detector array. In the present study, we performed Monte Carlo simulations to examine this method for various measurement conditions. EGS5 Monte Carlo simulation results confirm that this method is effective for measurements of a 22Na sealed point source using BGO scintillation detector arrays
