The environmental surveillance of the Risø environment was continued in July-December 2016. The mean concentrations in air were: 0.18±0.13 μBq m–3 of 137Cs, 2.30±0.68 mBq m–3 of 7Be and 0.21±0.12mBq m–3 of 210Pb (±1 standard uncertainty). The depositions by precipitation at Risø in the second half of 2016 were: 0.046±0.006 Bq m–2 of 137Cs, 494±50 Bq m–2 of 7Be, 24.9±2.2 Bq m–2 of 210Pb and <1.2 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was measured as 45 ± 2 nSv h–1 compared with 45 ± 6 nSv h–1 (±1 standard uncertainty) in the four zones around Risø.
