GAMMA SPECTROMETRY OF DUST SAMPLES
Dust samples were examined with respect to fission product content by means of a gamma spectrometer. It was possible to identify the gamma lines in the energy range between 0 and 1 Mev and these are assigned to the following elements: Nd/sup 147/, Ce/sup 141/, Ce/sup 144, Ba/sup 140/, La/sup 140/, R u/sup 106/, Ru/sup 103/ rmination of the absolute gamma and BETA activity from the photo-line surface is described with the aid of a spectrum for an aged dust sample. Quantitative results for dust samples for the months March to May 1959 and April 1961 are presented, and 2 possibilities for determination of the age of the flssion product mixture are discussed.
