| 摘 要： | 本文报导用活性炭盒吸附方法对香港室内氡浓度的测量结果及其浓度分布规律。对室内氡浓度与建筑物表面氡析出率的关系进行了分析研究。证实室内空气中的氡主要来源于建材中的镭,而氡浓度水平只决定于室内建筑物表面氡的析出率及通风状况。

| Abstract: | The indoor radon concentrations of more than 60 sites in Hong Kong is measu-red using activated charcoal canisters to identify the underlying distribution pattern.We have further investigated the probables strong relationship between the indoor radon concentrations and the radon exhalation rate from building surface.It has been found that the indoor radon comes mainly from radium in builbing materials,and that the radon concentration depends on the radon exhalation rate from indoor building surface and on the ventilation.It is also asserted that the radioativity level of building materials used in Hong Kong is increasing. |
