Radioactive liquid wastes of low-medium activity level are generated in radio immune assay (RIA) laboratories, which are also potentially infectious because of the pathogens from patient blood. The most common way of managing these wastes consists of a temporal storage, for partial radioactivity decay, followed by management by an authorised company. The object of this work is to study the viability of treating radioactive liquid wastes coming from RIA using membrane techniques in order to reduce their volume, which would mean an improvement from the radiological point of view and a decrease in management costs. This paper describes the results of some experiments carried out with RIA real wastes, by means of processes such as ultrafiltration and reverse osmosis. It has been proved that waste volume can be significantly reduced, obtaining a treated liquid that is free of pathogens and organic matter and with an activity level around the environmental background.
中低放射性水平的放射性液体废物产生于放射免疫分析（RIA）实验室，由于来自患者血液的病原体，这些废物也具有潜在传染性。处理这些废物最常见的方法是进行临时储存，以使部分放射性衰减，然后由授权公司进行处理。这项工作的目的是研究使用膜技术处理来自放射免疫分析的放射性液体废物以减少其体积的可行性，这将意味着从放射学角度有所改善，并降低管理成本。本文描述了通过超滤和反渗透等过程对放射免疫分析实际废物进行的一些实验结果。已证明可以显著减少废物体积，获得不含病原体和有机物且放射性水平接近环境本底的处理后液体。
