Abstract
An installation for decontaminating a radioactively contaminated surface with a dry mechanical abrasive includes an extractor for suction extraction of an extraction gas together with an abrasive/dust mixture produced during blasting. A separator separates the abrasive/dust mixture aspirated by the extractor into a dust fraction and a re-usable abrasive fraction. A storage bin is connected between the extractor and the separator. The storage bin includes a filter device having a filter for filtering the extraction gas flowing through the storage bin to the extractor, and a blowoff line to be connected to the filter device for blowing off the filter.
