The environmental surveillance of the Risø environment was continued in January - June 2008. The mean concentrations in air were: 0.45±0.39 μBq m–3 of 137Cs, 3.9±1.6 mBq m–3 of 7Be and 0.20±0.13 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the first half of 2008 were: 0.064 Bq m–2 of 137Cs, 349 Bq m–2 of 7Be, 19.9 Bq m–2 of 210Pb and 0.53 kBq m–2 of 3H.
The average background dose rate (TLD) at Risø (Zone I) was 64 nSv h–1 compared with 57±7.3 nSv h–1 (±1 S.D.; N = 4) in the four zones around Risø.
