Several researchers have examined and achieved favourable results in connection with the building industry's use of red mud extracted in large quantities from the processing of bauxite. These days more and more precedence is being given to limiting the radiological dose to the population. In this study carried out in Hungary, the use of red mud, bauxite, and clay additives recommended for the production of special cements, were examined from a radiological aspect. (226)Ra and (232)Th activity concentrations measured in Hungarian bauxite, red mud and clay samples were significantly similar with the levels for such raw materials mentioned in international literature. Taking radiation protection aspects into consideration, none of these products can be directly used for building construction. Taking Hungarian and international values into consideration, a small amount of red mud, not exceeding 15% could be used for brick production, for example as a colouring material. However, beyond this amount the standards for building materials would not be met. For the production of cements an even stricter limit needs to be determined when both bauxite and red mud are used.
几位研究人员对建筑行业使用从铝土矿加工过程中大量提取的赤泥进行了研究，并取得了良好的成果。如今，越来越重视限制公众的辐射剂量。在匈牙利进行的这项研究中，从放射学角度对推荐用于生产特种水泥的赤泥、铝土矿和粘土添加剂的使用进行了研究。在匈牙利铝土矿、赤泥和粘土样品中测得的（226）镭和（232）钍活度浓度与国际文献中提及的此类原材料的水平显著相似。考虑到辐射防护方面，这些产品都不能直接用于建筑施工。考虑到匈牙利和国际标准值，例如，不超过15%的少量赤泥可用于制砖，作为着色材料。然而，超过这个量就不符合建筑材料标准。对于水泥生产，当同时使用铝土矿和赤泥时，需要确定更严格的限制。
