title: Aerial measurement of radioxenon concentration off the west coast of Vancouver Island following the Fukushima reactor accident.
abstract: In response to the Fukushima nuclear reactor accident, on March 20th, 2011, Natural Resources Canada conducted aerial radiation surveys over water just off the west coast of Vancouver Island. Dose-rate levels were found to be consistent with background radiation, however a clear signal due to (133)Xe was observed. Methods to extract (133)Xe count rates from the measured spectra, and to determine the corresponding (133)Xe activity concentration, were developed. The measurements indicate that (133)Xe concentrations on average lie in the range of 30-70 Bq/m(3).
