Abstract : Thirty-two samples of the crude neon fraction collected at air lique-faction plants at Oberhausen and Munchen-Lohhof from 1958 to August 1963 have been processed to extract the atmospheric hydrogen contained therein. The preliminary conclusions arrived at from the tritium alone are (a) From the end of 1958 to the beginning of 1962 the concentration increased from T/H = 2.5 x 10 to -13th power to 5.5 x 10 to -13th power, i.e. by about a factor of two. (b) In late winter of 1961 or early spring of 1962 there was a sudden rise to T/H = 20 x 10 to -13th power. These results are compared with the predictions based on fallout data (1958-1961) and the amount of HTO deposited (during 1960-1962). Furthermore 10 samples of atmospheric methane, nine from Oberhausen (Germany) and one from Gary, Ind. (USA), were analysed for tritium. Finally, the tritium contents of the two chondrites PANTAR and KIEL were measured and found to be (0.55 = 0.05) and (0.45 = 0.03) dpm/gr, resp.
