GAMMA-RAY ANALYSIS OF ATMOSPHERIC DUST SAMPLES

Technical Report ·
OSTI ID:4245457

Gamma-ray spectra of dust samples from the atmosphere were plotted from measurements with a fivechannel analyzer. Peaks from fission products Zr-95, Nb- 95, Ru-103, Ce-141, Ce-144 and Cs-137, with halflives of several days and longer, were identified. The same peaks were found in a sample of house dust. Very long- lived fission products such as caesium-137 were not of sufficient activity to permit identification until the samples had decayed for several months. (auth)
