English Abstract This report summarizes the results of measurements of
radionuclides deposited at Bilthoven in the Netherlands in 1988. The total
depositions of 3H (1700+-40 Bq/m2), 7Be (1200+-50 Bq/m2), 210Pb (110+-
Bq/m2) and 210Po (25+-1 Bq/m2) were not substantially changed compared to
those in previous years. The same applies to the deposited gross alpha-
(36+-2 Bq/m2), gross beta- (103+-3 Bq/m2) and gross gamma-activity (185+-6
Bq/m2). The depositions of 134Cs and 137Cs were <5 Bq/m2 and <6 Bq/m2
respectively. In 1987 these depositions were <5 Bq/m2 and 12 Bq/m2. The
weekly deposition of gross gamma-activity, 3H and 7Be were correlated with
the amount of precipitation. In 1988 the consequences of "Chernobyl" were
no longer perceptible in the deposition in the
Netherlands.
