摘要
用EPA标准活性炭盒,现场收集建筑物表面析出的氡,并用γ谱测量氡的析出率。测定了香港不同地区不同年代10座建筑物100多个测量点的表面氡析出率。研究了不同楼层及装饰材料,裂缝等对析出的影响。
The radon exhaled from some building surfaces in Hong Kong is collected by means of the EPA-standardised activated charcoal canisters.The radon exhala- tion rates are obtained by analyzing the canisters using r-spectroscopy.Over 100 samples in 10 buildings of different years of history in different areas in Hong Kong are measured.The effect of floor levels.Covering materials and cracks in walls of the buildings on the exhalation rates is studied.
