Design and construction techniques are described for a 1.6 ha experimental reclamation plot consisting of a 1-m-thick slab of uranium mill tailings covered with various depths of overburden. A passive, activated charcoal device was developed and used for measurements of Rn flux at the soil surface. Observations on Rn flux vs overburden depth indicated that tailings covered with 1.5 m of revegetated or 0.3 m of bare overburden had Rn exhalation rates comparable to background. Vegetated subplots exhibited a significantly higher (often an order of magnitude) flux than the bare subplots. A positive correlation was observed between precipitation quantities and Rn flux.
描述了一个1.6公顷试验性复垦地块的设计和施工技术，该地块由一层1米厚的铀矿尾矿板组成，上面覆盖着不同深度的表土。开发了一种被动式活性炭装置，并用于测量土壤表面的氡通量。关于氡通量与表土深度的观测表明，覆盖有1.5米植被或0.3米裸表土的尾矿的氡析出率与背景相当。植被覆盖的子地块的通量明显高于裸子地块（通常高出一个数量级）。观测到降水量与氡通量之间存在正相关。
