摘要

研究了核电厂废物桶中放射性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 gamma scanning

TGS）技术装置的要求。

Abstract

In this paper

the algorithm for calibrating radionuclide 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.
