We measured radiofrequency (RF) radiation at the Järntorget square in the Stockholm Old Town in a new study recently published. In a previous study of the Old Town we found especially high RF radiation at that square. The maximum level in the present study was 11.6 V/m at the center of the square, where the antenna was focused. Järntorget’s mean value was 5.2 V/m, median 5.0 V/m, range 1.2-11.6 V/m.
Of interest is that this level can be compared to life-span carcinogenicity study on rats exposed to 1.8 GHz GSM environmental radiation performed at the Ramazzini Institute (RI) in Italy. A statistically significant increase in the incidence of malignant Schwannoma in the heart was found in male rats at the highest dose, 50 V/m. In treated female rats at the highest dose the incidence of malignant glial tumors was increased, although not statistically significant. In conclusion our study showed RF radiation levels at one square, Järntorget, in Sweden was only one order of magnitude lower than those showing increased incidence of tumours in the RI animal study. An increased cancer risk cannot be excluded for those working next to or at Järntorget for longer time periods.
These results indicate that it is pertinent to measure RF radiation levels in the environment and in homes. Such exposure levels should be declared for those intending to settle down in any dwelling.
