Management of hospital radioactive liquid waste: treatment proposal for radioimmunoassay wastes
نویسندگان
چکیده
<abstract> <p>Radioactive liquid wastes are produced at hospitals from diagnostic and therapeutic applications of radionuclides. The most usual management these is temporary storage the hospital for radioactivity decay and, then, discharge into sewage if not other pollutants present in waste, always after authorization corresponding institution. In some cases, radioactive have hazards, such as chemical or biological ones, which can be more dangerous than radiological hazard, do allow direct spite decaying activity below clearance level. Therefore, to treated condition before limit. This case radioimmunoassay (RIA), a laboratory technique that allows determine human substances very low concentrations (below 10<sup>-12</sup> g/mL), like hormones, using <sup>125</sup>I radionuclide. study summarizes hospitals, including conventional recent treatments applied. Furthermore, based on experimental results obtained with real RIA wastes, this work exposes proposal treatment ultrafiltration reverse osmosis membranes, determines suitable application according operational considerations.</p> </abstract>
