    The environmental surveillance of the Risø environment was continued in July - December 2010. The mean concentrations in air were: 0.34±0.26 μBq m–3 of 137Cs, 2.58±1.09 mBq m–3 of 7Be and 0.23±0.19 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2010 were: 0.045 Bq m–2 of 137Cs, 744 Bq m–2 of 7Be, 47.0 Bq m–2 of 210Pb and <1.2 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was 65 nSv h–1 compared with 58 ± 7 nSv h–1 (±1 S.D.; N = 4) in the four zones around Risø.
