    Abstract

    The environmental surveillance of the Risø environment was continued in July - December 2011. The mean concentrations in air were: 0.25±0.19 μBq m–3 of 137Cs, 2.81±1.71 mBq m–3 of 7Be and 0.23±0.18 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2010 were: 0.102 Bq m–2 of 137Cs, 757 Bq m–2 of 7Be, 75.1 Bq m–2 of 210Pb and < 0.8 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was 67 nSv h–1 compared with 66 ± 14 nSv h–1 (±1 S.D.; N = 3) in the four zones around Risø.
