The authors did two similar experiments, but used different SARs. One hundred mice prone to mammary tumours were exposed to 2450 MHz RF radiation for 20 hours per day for 18 months, and compared to 100 sham-exposed animals.
In the first experiment the whole body average SAR was 0.3 W/kg. There was no difference between the radiated animals and the controls in incidence of mammary tumours, latency to tumour onset, tumour growth rate, or animal survival.
the second study the mice had a whole body average SAR
of 1.0W/kg. Once again there were no differences between
the groups in the above parameters.
