成都地区地坪基础土壤中氡浓度分布规律的初步探讨

Primary research on Rn distribution pattern in the soil of groundwork in Chengdu area

在对居室内空气质量的检测中,居室空气中氡浓度的高低是一个重要指标,为了降低低层住宅空气中氡的浓度,在新建住宅的施工中,必须首先对住宅的地坪基础进行氡浓度的检测,以避免房屋建成之后,低层住宅中氡浓度的偏高。本文就成都地区地坪基础的施工中氡浓度的变化规律作一初步探讨。

Rn concentration is an important factor in the indoor air quality survey. In order to decrease Rn concentration in lower residence, Rn concentration in the soil of groundwork has to be surveyed to avoid high Rn concentration in the residence to be built. The variation rules of Rn concentration in the soil of the groundwork in Chengdu area is discussed from different angles
