The environmental surveillance of the Risø environment was continued in January-June 2016. The mean concentrations in air were: 0.28±0.17 μBq m–3 of 137Cs, 2.58±1.21 mBq m–3 of 7Be and 0.23±0.15 mBq m–3 of 210Pb (±1 S.D.). The depositions by precipitation at Risø in the first half of 2016 were: 0.058±0.007 Bq m–2 of 137Cs, 474±47 Bq m–2 of 7Be, 27.5±2.5 Bq m–2 of 210Pb and <0.7 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was measured as 59 nSv h–1 compared with 52 ± 2 nSv h–1 (±1 S.D.) in the four zones around Risø.
