| 为研究矿物组成对块状花岗岩氡析出的影响,本文将采集自湘东南地区的花岗岩样品制备成长方体岩块并包裹5个面,测量了半无限大介质的表面氡析出率。结果显示,天然花岗岩样品的表面氡析出率都较高,花岗岩矿物组成与其表面氡析出率的皮尔逊相关系数大小依次为石英>云母>钾长石>斜长石,其中石英、云母和钾长石表现出正相关关系,斜长石则呈负相关关系。通过本次研究,加深了矿物组成对花岗岩氡析出制约的理解,并为我国人居环境氡气防治以及环境氡示踪应用提供理论支持。 |
| 英文摘要: |
| 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 surface radon elution rate of semi-infinite medium. The findings indicate that the surface radon elution rates of natural granite minerals are uniformly elevated. The surface radon elution rate and the mineral composition of granite have Pearson correlation coefficients that are in the following order: quartz > mica > potassium feldspar >clay > plagioclase. Plagioclase exhibits a negative correlation, whereas quartz, mica, and potassium feldspar exhibit positive correlations. The comprehension of the detrimental mineral makeup of radon in granite has increased as a result of this work, which has also offered theoretical justification for the use of environmental radon tracers and the prevention and control of radon gas in residential settings in China. |
