This note reports radon gas pore diffusion coefficient measurements for residential concretes from Florida, ranging in age from 12 y to 45 y. The coefficients ranged from 1.5 x 10(-7) m2 s-1 to 5.5 x 10(-7) m2 s-1. On the average, these values are about a factor of 1.6 higher than average values previously reported for new residential concretes in Florida.
本报告介绍了对佛罗里达州使用年限在12年至45年之间的住宅混凝土中氡气孔隙扩散系数的测量结果。系数范围为1.5×10⁻⁷平方米每秒至5.5×10⁻⁷平方米每秒。平均而言，这些值比之前报道的佛罗里达州新建住宅混凝土的平均值高出约1.6倍。
