The environmental surveillance of the Risø environment was continued in July-December 2019. The mean concentrations in air were: 0.21±0.13 μBq m–3 of 137Cs, 3.30±1.42 mBq m–3 of 7Be and 0.43±0.35mBq m–3 of 210Pb (±1 standard uncertainty). The depositions by precipitation at Risø in the second half of 2018 were: 0.048±0.007 Bq m–2 of 137Cs, 418±42 Bq m–2 of 7Be, 26.0±3.0 Bq m–2 of 210Pb and <1.8 kBq m–2 of 3H.
The average background dose rate (TLD) at Risø (Zone I) was measured as 99±25 nSv h–1 compared with 73±4 nSv h–1 (±1 standard uncertainty) in the four zones around Risø.
