Abstract
Measurements of anthropogenic I-129 and Ca-41 in two Greenland firn co res spanning the years 1935 to 1989 have been performed by accelerator mass spectrometry. The two sets of data points measured for I-129 sho w a discrepancy and prevent definitive conclusions. One of the sets in dicates no large increase of I-129 concentrations in contrast to preci pitation at lower latitudes. Data on the Ca-41 profile are preliminary and show a few points markedly above background. The feasibility of d etection of Sr-90 in the environment by accelerator mass spectrometry is studied and first results are reported.
