    The environmental surveillance of the Risø environment was continued in July - December 2008. The mean concentrations in air were: 0.27±0.15 μBq m–3 of 137Cs, 2.8±0.83 mBq m–3 of 7Be and 0.18±0.13 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2008 were: 0.046 Bq m–2 of 137Cs, 456 Bq m–2 of 7Be, 28.8 Bq m–2 of 210Pb and <1.0 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was 69 nSv h–1 compared with 56±6.2 nSv h–1 (±1 S.D.; N = 4) in the four zones around Risø.
