摘　　要：通过活性炭-γ能谱法测量表面经过预处理后的不同建材样品氡析出率,计算求得该建材氡固有析出率.实验结果表明,建材固有氡析出率能真实反映出建材氡析出率的情况且不受建材自身形状因素的影响,不失为一种准确可靠测量建材表面氡析出率值的方法.Radon exhalation rate from different building materials after pretreatment were measured using the charcoal canister method for calculating radon inherent exhalation rate. The results showed that radon inherent exhalation rate can represent the true radon in building materials and not be affected by the shape factor of building materials. It is simple and reliable for the method to calculate radon inherent exhalation rate. It can be regarded as a method for accurate measurements of radon exhalation rates for building materials.
