Abstract

The environmental surveillance of the Risø environment was continued in January-June 2017. The mean concentrations in air were: 0.29±0.28 μBq m^–3 of ¹³⁷Cs, 2.92±0.92 mBq m^–3of ⁷Be and 0.27±0.23 mBq m^–3 of 210Pb (±1 S.D.). The depositions by precipitation at Risø in the first half of 2017 were: 0.037±0.006 Bq m^–2 of ¹³⁷Cs, 608±61 Bq m^–2 of ⁷Be, 12.7±1.1 Bq m^–2 of ²¹⁰Pb and <0.9 kBq m^–2 of ³H. The average background dose rate (TLD) at Risø (Zone I) was measured as 51 nSv h^–1 compared with 48 ± 3 nSv h^–1 (±1 S.D.) in the four zones around Risø.
