The 222Rn emanation power of building materials, soil and rock samples is determined by collecting exhalated radon on activated charcoal. Median values are 0.2 for dry soils and stones, 0.06 for sand, 0.025 for bricks, 0.006 for ceramic tiles, 0.008 for mineral slag and 0.3 for gypsum. The emanation power of soil rises with water content, in accordance with literature. For water content above 10% the emanation power of soil is about twice as high as for dry soil.
建筑材料、土壤和岩石样品的222Rn发散能力是通过在活性炭上收集呼出的氡来测定的。干燥土壤和石头的中值为0.2，沙子为0.06，砖块为0.025，瓷砖为0.006，矿渣为0.008，石膏为0.3。根据文献，土壤的发散能力随含水量增加而升高。对于含水量超过10%的土壤，其发散能力约为干燥土壤的两倍。
