    Abstract

    The environmental surveillance of the Risø environment was continued in July - December 2014. The mean concentrations in air were: 0.31±0.24 μBq m–3 of 137Cs, 2.70±1.13 mBq m–3 of 7Be and 0.28±0.22 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2014 were: 0.056 Bq m–2 of 137Cs, 730 Bq m–2 of 7Be, 76.7 Bq m–2 of 210Pb and < 1.2 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was 42 nSv h–1 compared with 51 ± 5 nSv h–1 (±1 S.D.; N = 4) in the four zones around Risø.
