Environmental radiofrequency radiation at the Järntorget Square in Stockholm Old Town in Sweden compared with results on tumour risks in rats exposed to 1.8 GHz base station environmental emissions

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.

  1. There is a difference from 11,6 V/M to 50 V/M. How can the Ramazzini study then tell us anything useful about being exposed to radiation on a place like this?

    • Usually, a safety factor is used to take care of older persons, children, disabled etc. We discuss that in the article, see page 51:

      Specifically, a safety factor of ten was applied to reduce the SAR threshold of 100 to 10 W/kg. To provide for an additional margin of safety for the general public, an extra factor of five was introduced to arrive at 2 W/kg over 10 g of contiguous tissue, including the eye’.Using the same logic in safety factors as for SAR regarding the RI results would yield 2.5 V/m as a safety level. Thus, our results at Järntorget exceed that RF radiation magnitude.

      Thus, using the same safety factor for the radiofrequency radiation at Järntorget shows that the level is too high.
