The 35S content in atmospheric deposition, aerosol and rain water was determined about every 10 days for a year with 7Be, 32P and some stable elements. Average 35S concentrations were 110 mBq·m-2·d-1 for atmospheric deposition, 0.078 mBq-m-3 for aerosol in surface air and 45 mBq·1-1 for rain water. The ratios of 7Be/35S were abnormally low, although most of 32P/7Be showed the reasonable values corresponding to the residence times from 10 to 60 days. The excess 35S suggests an external source of 35S or/and a faster cycle of 35S than that of 7Be and 32P.
