The environmental surveillance of the Risø environment was continued in July - December 2013. The mean concentrations in air were: 0.20±0.08 μBq m–3 of 137Cs, 2.23±0.64 μBq m–3 of 7Be and 0.16±0.08 μBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2012 were: 0.048 Bq m–2 of 137Cs, 436 Bq m–2 of 7Be, 31.3 Bq m–2 of 210Pb and < 0.7 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was 44 nSv h–1 compared with 43 ± 9 nSv h–1 (±1 S.D.; N = 4) in the four zones around Risø.
