We have published results on measurements of radiofrequency (RF) radiation in central parts of Stockholm, Sweden. The published article can be found here. Especially high levels were found at the Hay Market and Sergel Plaza; mean levels 10,728 and 7,768 microWatt/m2, respectively. Also at central streets high ambient RF radiation was found from nearby base stations.
The figure below shows the result for the Hay Market. We have inserted the 30-60 microWatt/m2 line for lowest level of biological effects (red line).
