The Effect of Element composition ratio for Determination Ash content in Coal by a Scattered γ-ray method.
抄録
A scattered γ-ray method was investigated to determine ash content in coal. The R/C value, ratio of Rayleigh to Compton scattered γ-ray, is related to the effective atomic number which corresponds with the element composition in coal. In this paper, the theoretical R/C value was calculated under varing with the change in ash content. It was shown unquantitatively at even constant ash content that the R/C value varies with the change in content of ash such as Fe_2O_3, CaO and others.
