    Atmospheric tracer tests and assessment of a potential accident at the National Medical Cyclotron Camperdown, NSW, Australia
    (Australian Nuclear Science and Technology Organisation, 1994-08) Clark, GH; Bartsch, FJK; Muller, HH; Stone, DJM
    In order to assess the impact of a potential atmospheric release of radionuclides from the National Medical Cyclotron facility in Camperdown an atmospheric tracer release sampling and analysis system using SF6 was developed. During eight experiments conducted in a variety of meteorological conditions ten samplers were located in the vicinity of the Cyclotron building and other nearby buildings on the rapid downward movement of the tracer gas plume. The atmospheric dilution factors which lead to the highest observed air concentrations were then applied to the releases of I123and Xe123 from a potential accident scenario in order to assess the impact on nearby receptors. Even given the conservative assumptions about the release of I123 the estimated radiation doses were at least an order of magnitude below the international standards for doses to member of the public.
