Abstract

The environmental surveillance of the Risø environment was continued in July - December 2012. The mean concentrations in air were: 0.32±0.31 μBq m^–3 of ¹³⁷Cs, 3.04±0.99 mBq m^–3 of⁷Be and 0.22±0.18 mBq m^–3 of ²¹⁰Pb (±1 S.D.; N = 26). The depositions by precipitation at Risø in the second half of 2012 were: 0.039 Bq m^–2 of ¹³⁷Cs, 615 Bq m^–2 of ⁷Be, 40.3 Bq m^–2 of ²¹⁰Pb and < 0.6 kBq m^–2 of ³H. The average background dose rate (TLD) at Risø (Zone I) was 54 nSv h^–1 compared with 58 ± 8 nSv h^–1 (±1 S.D.; N = 3) in the four zones around Risø.
