运用无机盐饱和溶液控制密闭容器内建材砖的含水率,采用活性炭盒法比较不同含水率对建材砖氡析出率的影响.结果表明,随着含水率的升高,氡析出率先升高后降低,当含水率为4%左右时,氡析出率达到最大值为32.31±2.84mBq.m~(-2).s~(-1).

In the paper, The moisture of building material bricks was controlled by the saturation solution of inorganic salt which were deposited in a obturator. The activated charcoal method was used to compare the influence of radon exhalation rate of building material bricks on different moistures condition. From the result, it can be found that with the increasing of mositure, the radon exhalation rate is increasing at first and then discreasing, when the mositure is about 4%, and the h...
