The whole-body counting facility at the Swedish Radiation Safety Authority after relocation.
The whole-body counting (WBC) facility at the Swedish Radiation Safety Authority was rebuilt in a new location during 2004-2007. In this paper, the relocated WBC facility, its background and the detectors' response are described. The report on the limit of detection is given. The report on a first round of measurements on a non-contaminated group of 24 persons for control of Cesium 137 ((137)Cs) and potassium 40 ((40)K) is also presented. The results of the measurements of the control group compared with those from the previous facility revealed biased values up to 5 %, being this more evident for (40)K, which was underestimated. The correction applied and the determination of the measurement uncertainty are described.
