Exposure in public places
To discover how much wireless radiation people are exposed to in public spaces, Swedish researchers measured the fields present in the Stockholm Central Railway Station in Sweden. They took measurements in over 1600 locations and found that exposures measured bwtween 2,817 and 4,891 uW/m2. That's a much higher exposure than the 3-6 uW/cm2 recommended by the independent authors of the BioInitiative Working Group.
The study was published in August 2016 and more details about it can be found here.
