Abstract

The environmental surveillance of the Risø environment was continued in July-December 2017. The mean concentrations in air were: 0.14±0.11 μBq m^–3 of ¹³⁷Cs, 2.27±0.72 mBq m^–3 of ⁷Be and 0.20±0.14 mBq m^–3 of ²¹⁰Pb (±1 standard uncertainty). The depositions by precipitation at Risø in the second half of 2016 were: 0.031±0.005 Bq m^–2 of ¹³⁷Cs, 539±54 Bq m^–2 of 7Be, 39.0±4.0 Bq m^–2 of ²¹⁰Pb and <1.2 kBq m^–2 of ³H. The average background dose rate (TLD) at Risø (Zone I) was measured as 49 ± 7 nSv h^–1 compared with 53 ± 4 nSv h^–1 (±1 standard uncertainty) in the four zones around Risø.
