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.33 pnl16milieudepositieregenwaterradioactiviteitmonitoring; tsjernobyl environmentdepositionrain-waterradioactivity; monitoringchernobylReport2012-12-12
