Abstract (en)
Apparatus for treating waste water containing radionuclides resulting from medical therapy or diagnosis comprises a buffer tank into which the water is fed. This can be emptied in batches via a metering tank with an integral probe, which measures the amount of radioactivity and/or nuclides it contains, into a storage tank. Apparatus for treating waste water containing radionuclides resulting from medical therapy or diagnosis comprises a buffer tank (1) into which the water is fed. This can be emptied in batches via a metering tank (19) with an integral probe (20), which measures the amount of radioactivity and/or nuclides it contains, into a storage tank (32). A computer (31) uses the data from the probe to control the volume of water in the storage tank and its total activity, so that the tank can be emptied after a precalculated decay time. In one embodiment of the invention several storage tanks are used, arranged in parallel. Each of these is used for a different level of radioactivity and/or different nuclides. The buffer tank forms part of a vacuum system.
Abstract (de)
Bei derartigen Abklinganlagen ist vorgesehen, daß das Abwasser einem Puffertank zuführbar ist, der unter Zwischenschaltung eines Meßtanks mit einer Meßsonde zur Radioaktivitäts- und/oder Nuklidbestimmung in einem Sammeltank entleerbar ist. Die ermittelten Meßdaten werden einer zugeordneten Steuer- und Recheneinheit zur Volumen- und Aktivitätsbilanzierung des beschickten Sammeltanks zugeführt. In dieser Steuer- und Recheneinheit wird ein Abgleich zu einer eingestellten Radioaktivität nach einer Abklingzeit vorgenommen und der Sammeltank dann entleert. <IMAGE>
