abstract = "The environmental surveillance of the Ris{\o} environment was continued in January - June 2010. The mean concentrations in air were: 0.99±1.11 μBq m–3 of 137Cs, 4.56±2.71 mBq m–3 of 7Be and 0.49±0.57 mBq m–3 of 210Pb (±1 S.D.; N = 26). The depositions by precipitation at Ris{\o} in the first half of 2010 were: 0.095 Bq m–2 of 137Cs, 521 Bq m–2 of 7Be, 48.2 Bq m–2 of 210Pb and <0.5 kBq m–2 of 3H. The average background dose rate (TLD) at Ris{\o} (Zone I) was 106 nSv h–1 compared with 91 ± 4 nSv h–1 (±1 S.D.; N = 4) in the four zones around Ris{\o}.",
