Gamma ray thickness measurement

Abstract

Gamma ray attenuation coefficients are different in diverse condition after its penetration through different components. This character has been widely used in worldwide researches for kinds of measurement treatments in medicine, and industrial detection etc. This study is mainly about one of applications of gamma ray measurement which is called gamma ray thickness measurement. Moreover, this paper also introduces principles of gamma ray detection methods and attenuation principles as well as digging its best measurement condition of the correlations. Continually, the paper will state a derivation process of the best condition by calculations.
