天然花岗岩中矿物组成对氡析出率的影响研究
Study on the Influence of Mineral Composition of Granite on Radon Exhalation Rate
摘要
Abstract
This study examined the influence of mineral composition on radon elution from enormous granite by utilizing granite samples sourced from the southeastern Hunan to create growing cube rock blocks,which were wrapped on five sides,and assessed the sur-face radon elution rate(simulate semi-infinite medium).The findings indicate that the sur-face radon elution rates of natural granite minerals are uniformly elevated.The surface ra-don elution rate and the mineral composition of granite have Pearson correlation coefficients that are in the following order:quartz＞mica＞potassium feldspar＞plagio-clase.Plagioclase exhibits a negative correlation,whereas quartz,mica,and potassium feldspar exhibit positive correlations.关键词
