Abstract

Management of radon emissions from uranium tailings ponds is crucial for public safety. Calcium lignosulfonate (CaLS)-modified red clay is explored as a radon mitigation material in this study. Experiments showed that a 6% CaLS concentration with a three-day curing period optimized radon adsorption, reduced exhalation rates by 30–47% and blocked up to 98.9% of radon. This modification also enhanced the soil strength. The use of CaLS-modified red clay in tailings dams significantly reduced radon emissions, and lowered health risks.

木质素磺酸钙改性红粘土减氡效果的实验研究

铀尾矿池的氡排放管理对公共安全至关重要。本研究探讨了木质素磺酸钙改性红粘土作为一种减氡材料。实验表明，当CaLS浓度为6%，固化时间为3天时，其对氡的吸附效果最佳，呼气率降低30-47%，氡截留率高达98.9%。这种改良也提高了土的强度。在尾矿坝中使用cals改性红粘土可显著减少氡排放，降低健康风险。
