Ernst H, Ebert S, Kuster N, et al. (2007):
The aim of
this study was to assess potential carcinogenic effects on mice
of exposure to RFR from GSM (902MHz) and DCS (1747 MHz) handsets.
Restrained mice, after a period of acclimatization, were exposed
for 2 h per day, 5 days per week, over a period of 2 years. Three
different whole-body averaged SAR levels were used - 0.4, 1.2,
and 4.0 mW/g bw. Groups of mice were also sham-exposed.
no differences between the sham and exposed groups in food intake,
body weight gain, mortality, hematological analysis, or organ
no differences in the incidence of any particular tumour type
in the RF exposed groups as compared to the sham exposed groups.
While the incidences of hepatocellular carcinoma were similar
in RFR and sham exposed groups, the incidence of liver adenomas
decreased with increasing dose levels. The incidences in the
high dose groups were statistically significantly different from
those in the sham exposed groups. The observed tumour rates were
within the range of historical control data.
conclusion, the present study produced no evidence that the exposure of male
and female B6C3F1 mice to wireless GSM and DCS radio frequency signals at a
whole body absorption rate of up to 4.0 W/kg resulted in any adverse health
effect or had any cumulative influence on the incidence or severity of neoplastic
and non-neoplastic background lesions, and thus the study did not provide any
evidence of RF possessing a carcinogenic potential".
