Abstract
In an airlock system, through which drums containing radioactive material are transferred into a containment area, a passage has an intermediate region, of reduced cross section relative to the inlet and outlet ends of the passage. The passage has a convergent inlet region and a divergent outlet region leading, respectively, to and from the intermediate region. The passage functions in the manner of a venturi so that an airstream is caused to flow along the passage towards the containment so as to inhibit the escape of atmosphere therefrom. A roller conveyor transfers the items through the airlock system and a detector monitors the atmosphere in the passage.
