Combined backscatter and transmission method for nuclear density gauge

摘要

Nowadays, the use of nuclear density gauges, due to the ability to work in harsh industrial environments, is very common. In this study, to reduce error related to the p of continuous measuring density, the combination of backscatter and transmission are used simultaneously. For this reason, a~(137)Cs source for Compton scattering dominance and two detectors are simulated by MCNP4C code for measuring the density of 3 materials. Important advantages of this combined radiometric gauge are diminished influence of μ and therefore improving linear regression.
