    Risø environment was continued in July - December 2009. The mean concentrations in air were: 0.34±0.19 μBq m–3 of 137Cs, 3.55±1.09 mBq m–3 of 7Be and 0.25±0.11 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2009 were: 0.031 Bq m–2 of 137Cs, 586 Bq m–2 of 7Be, 34.2 Bq m–2 of 210Pb and < 1.0 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was 72 nSv h–1 compared with 63 ± 5 nSv h–1 (±1 S.D.; N = 4) in the four zones around Risø.
