    Abstract

    Experimental measurements of the dynamic as well as the static spread pattern of large amounts of airborne radioactivity suddenly released in the DR3-reactor shell at Risø were made by means of releases of 41Ar. A method of data treatment was worked out by which the data from the different measurement points and releases could be standardized and therefore directly compared. An evaluation of the preferred ventilation conditions and evacuation routes in the case of a sudden release of activity was made. Only one or two minutes elapse before significant increases in the activity concentrations ar e observed in and around the crane well. The control room, the elevator stairs and the personnel air lock are not affected until after several minutes. Recommendations on the present system are given.
