We measured the radiofrequency (RF) radiation at central parts in Stockholm, Sweden in March and April 2017. The same measurement round tour was used each time. We used EME Spy 200 for the measurements as in our previous studies in Stockholm. The results were based on 11,482 entries, corresponding to more than 12 h measurements. The total mean level was 5,494µW/m(median 3,346; range 36.6-205,155). The major contributions were down links from LTE 800 (4G), GSM + UMTS 900 (3G), GSM 1800 (2G), UMTS 2100 (3G) and LTE 2600 (4G). Regarding different places, the highest RF radiation was measured at the Hay Market with a mean level of 10,728µW/m(median 8,578; range 335-68,815). This is a square used for shopping, and both retailers and visitors may spend considerable time at this place. Also, the Sergel Plaza had high radiation with a mean of 7,768µW/m. All measurements exceeded the target level of 30-60µW/mbased on non-thermal (no heating) effects, according to the BioInitiative Report. Based on short-term thermal effects, The International Commission on Non-Ionizing Radiation Protection established guideline 2 of 10 W/m(2,000,000-10,000,000µW/m) depending on frequency in 1998, and has not changed it despite solid evidence of non-thermal biological effects at substantially lower exposure levels. These environmental RF radiation levels are expected to increase with the introduction of 5G for wireless communication.
