Uncertainty Analysis of in Situ Object Count System Activity Measurement for Standard 200 L Barrel
摘要
Abstract
Monte-Carlo method was used to evaluate the uncertainty of the activity mea-surement which was caused by the random distribution of radioactive substance in standard 200 L barrel in normal in situ object count system. The correction coefficient of the measurement results of ten different nuclide species in four different densities was calculated by Monte-Carlo method in simulation models.关键词
