    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.

    General aspects of meteorology and wind flow patterns at the National Medical Cyclotron site Camperdown, NSW, Australia.
    (Australian Nuclear Science and Technology Organisation, 1994-06) Clark, GH; Bartsch, FJK
    As part of an assessment into the consequences of a potential accident at the National Medical Cyclotron Camperdown NSW. Australia two meteorological stations were installed to monitor the winds temperatures and atmospheric dispersion conditions. The data will be used to assess environmental impacts of the Cyclotron's operation. In spite of the relatively poor performance of the stations the wind data indicated significant effects of local buildings and the general urban surface roughness features. The prevailing winds during the study were from the north-north-west at night and south-south-west or north-east sea breezes during the day. Atmospheric stability/dispersion categories were typical of an urban heat island location.
