钚的同位素

根据相对效率法的原理，利用PC/FRAM分析软件，开展了用高分辨γ谱仪测量密封容器中钚材料的同位素丰度和年龄的实验研究。

Based on the concept of relative detection efficiency , some experiments have been conducted to measure the isotopic abundance and the age of the plutonium material in a sealed container by a high-resolution γ - ray spectrometer .

研究结果表明，同位素丰度和年龄的分析精度随能谱测量精度的提高而提高，如果能谱的测量精度不够，通过PC/FRAM分析得出的钚材料的同位素丰度和年龄有偏低的可能。

The study shows that the analysis precision of the isotopic abundance and the age will rise as the spectral measurement precision increases , and that if the spectral measurement precision is not enough , the analyzed results by the PC / FRAM software might be lower .

然后将实际的钚样品放入容器，通过容器外各种特征γ射线强度的测量可以推算出钚的同位素成分；

Once the relative efficiency ratio for the container is known , the isotopic components for plutonium can be induced by assigning the real γ ray source in the sample and analyzing the characteristic γ ray intensity outside the container .
