研究了核电厂废物桶中放射陛核素活度测量校正算法，并用计算机以1：2模型模拟核电厂实际废物桶来验证所研究的算法。结果表明：与现有的算法相比，本研究的算法误差较小。而且算法的实际应用性强，能很好满足层析γ扫描（Tomographic gammas canning，TGS）技术装置的要求。

英文摘要：

In this paper, the algorithm for calibrating mdionuclide activity of waste barrels from a nuclear power plant is studied. A simulations to validate the algorithm was done on a model of 1：2 ratio to an actual waste barrel at a nuclear power plant. The results indicate that the image reconstruction errors are smaller than other algorithms. Further more, this method, with strong practicability, can well meet the requirements of TGS device.
