"In Situ Expression of Heat-Shock Proteins and 3-Nitrotyrosine in Brains of Young Rats
Exposed to a WiFi Signal In Utero and In Early Life. Radiat Res. 2013 May 10. [Epub ahead of
print]
The bioeffects of exposure to Wireless High-Fidelity (WiFi) signals on the developing nervous
systems of young rodents was investigated by assessing the in vivo and in situ expression levels of three
stress markers: 3-Nitrotyrosine (3-NT), an oxidative stress marker and two heat-shock proteins (Hsp25 and
10
Hsp70).
These biomarkers were measured in the brains of young rats exposed to a 2450 MHz WiFi signal by
immunohistochemistry. Pregnant rats were first exposed or sham exposed to WiFi from day 6 to day 21 of
gestation.
In addition three newborns per litter were further exposed up to 5 weeks old. Daily 2-h exposures
were performed blind in a reverberation chamber and whole-body specific absorption rate levels were 0,
0.08, 0.4 and 4 W/kg.
3-NT and stress protein expression was assayed in different areas of the hippocampus
and cortex. No significant difference was observed among exposed and sham-exposed groups. These results
suggest that repeated exposure to WiFi during gestation and early life has no deleterious effects on the brains
of young rats."
Without the power density data, it's difficult to ascertain how strong the signal was. It could have been 1W, which would show no effects, most likely. If it was a common wifi power density, like those our children are being exposed to in schools, we'd possibly get a different result.
