铀矿

Thus, SRB were likely to reduce sulfates to sulfides simultaneously with petroleum oxidization, and directly or indirectly reduce hexavalent uranium U to tetravalent uranium U to precipitate pitchblende.

于是，利用烃类作为生存的碳源，硫酸盐还原菌将硫酸盐还原的同时，直接或间接地把六价铀U还原成四价铀U，导致沥青铀矿形成。

The results show that thermoluminescent anomalies, whose two edges are higher and the middle is lower, indicate the uranium deposit, the rapidity step of natural voltage indicates the transitive section of oxidation-reduction.

通过室内和野外实测，结果表明土壤天然热释光异常曲线矿体边缘高值，矿体上方低值异常的曲线特征反映了铀矿化存在的可能；中间低值段越宽，起伏变化越小，矿化相对较好；低值段宽，但起伏变化相对较大，则矿体连续性变差；中间低值段狭窄，反映了矿化较差或没有矿化。

The sandstone uranium deposit s occur in the coal-bearing leuco-clastic formation,which developed in Neogene basins and unconformably overlays the granitic basement.

以花岗质岩石为基底的晚第三纪盆地中堆积了浅色含煤碎屑岩建造，砂岩铀矿即产于其中。

From tell on the other hand, the maturity that adopts smelt metal technique as uranium and improve, through reclaiming this part resource undertakes uranous product is produced, made full use of original production facilities and equipment, environmental impact is little and economic benefits is obvious.

从另一方面讲，随着铀矿采冶技术的成熟与改进，通过回收这部分资源进行铀产品生产，充分利用了原有生产设施与设备，环境影响小而又经济效益明显。

Reclaim to involve the resource of mine stopping uranium ahead of schedule as far as possible, can increase rare uranous resource not only reclaim utilization rate, reduce waste, and be helpful for retiring be opposite after processing retire the management of the project.

尽量回收提前关停铀矿山的资源，不仅可以提高稀有铀资源的回收利用率，减少浪费，而且有利于退役治理后对退役工程的治理。

These results are valuable for reasonably determining the radon eduction rate in remedial action on decommissioned uranium mine.

其结果对铀矿山退役治理中氡析出率的合理确定具有一定的参考价值。

Australia used to, but its new government has gone cooler on the idea. Uranium-rich Namibia, a non-member, hankers after its own enrichment business too.

澳大利亚曾经也是这样的国家，但她的新政府在这个问题上已变得更加冷静，但像纳米比亚这样一个铀矿资源丰富的国家，却也渴望能拥有自己的铀浓缩贸易。

This paper briefly reviews the research history of the lung cancer due to Radon and its progenies in the past hundreds years,then presents the relationship between risk of lung cancer and radon and its progenies inbreathed by uranium miners.

简要回顾氡致肺癌的长时间认识过程和研究历史，简述了当年铀矿工人和矿工吸入氡及其子体与肺癌发病率的关系，指出环境中氡的危害。

There are many uranium mineralized and anomaly occurrences with great prospect in this basin .

通过多年在该盆地的地质工作，在盆内发现了众多的铀矿化异常点，呈现良好的找矿前景。

Calculating results for fixed position of uranium mineralizing range in Dingshan area is in accord with the results of geological drill in this area.

计算得到的北准顶山预测区铀矿化地段空间定位范围与实际钻探验证结果具有较好的一致性。
