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