本文讨论了几种腐蚀控制策略实施后，沉积材料中镭的掺入和氡释放的探索性研究。其中包括碳酸钙沉淀和磷酸盐添加。含磷涂层和沉积物尤其令人担忧，因为众所周知，含磷矿物会积累大量镭。作者特别感兴趣的是在实验困难的条件下测定沉积物中的镭含量，在这种条件下，会形成少量沉积物，并且实际上会从水中去除少量镭，但每单位质量沉积物中的镭含量可能非常高。 这项研究表明，添加磷酸盐和磷酸锌可能会增加所产生沉积物中镭的积累和氡的释放。观察到的q值足够高，表明存在潜在问题，以及两项未决法规之间可能存在的联系，一项针对氡，另一项针对铅和铜。

This paper discusses exploratory studies on the incorporation of radium into and radon release from deposit material formed when several corrosion control strategies are implemented. These included precipitation of calcium carbonate and phosphate addition. Phosphate containing coatings and deposits are a particular concern because it is well known that phosphate bearing minerals can accumulate large amounts of radium. The authors are particularly interested in determining the radium content of the deposits under the experimentally difficult conditions where small amounts of deposits are formed and little radium is actually removed from the water, but where the amount of radium per unit mass of deposit could be very high. This investigation shows that addition of phosphate and zinc phosphate can potentially increase the accumulation of radium and release of radon from resulting deposits. The observed q values are sufficiently high to indicate a potential problem and possible linkage between two pending regulations, one for radon and the other for lead and copper.
