    dct:description "We have developed a simple method for separating the gamma radiation due to 137Cs from that due to natural sources using conventional 4-channel airborne gamma-ray spectrometry. The method uses the fact that whilst the 137Cs photopeak falls within the conventional total-count window, it occurs well below the three windows used to monitor naturally present K, U and Th .  Since we know the shapes of the K, U and Th spectra at the survey altitude, we can use these spectra and the 3-channel elemental count-rates to predict a total-count count-rate due to natural sources of radiation. The total-count count-rate due to caesium is then simply the difference between the measured total-count count-rate and the predicted natural source contribution to the total-count window. The method maps the distribution of 137Cs contamination in the vicinity of the Maralinga nuclear test site very effectively." ;
