Monitoring of radioactivity in deposition. Results for 1988.

Abstract niet beschikbaarThis 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
