Plain English Summary
Researchers exposed pregnant rats and their offspring to eight different wireless communication frequencies (from cell phones to WiFi) for 20 hours daily throughout pregnancy and early development. They found no adverse effects on pregnancy outcomes, offspring development, memory function, or reproductive ability across two generations of rats. This study suggests that simultaneous exposure to multiple wireless frequencies at communication signal levels may not harm reproductive health or early development.
Study Details
In everyday life, people are exposed to radiofrequency (RF) electromagnetic fields (EMFs) with multiple frequencies. To evaluate the possible adverse effects of multifrequency RF EMFs, we performed an experiment in which pregnant rats and their delivered offspring were simultaneously exposed to eight different communication signal EMFs (two of 800 MHz band, two of 2 GHz band, one of 2.4 GHz band, two of 2.5 GHz band and one of 5.2 GHz band).
Thirty six pregnant Sprague-Dawley (SD) 10-week-old rats were divided into three groups of 12 rats: ...
No abnormal findings were observed in the dams or F1 offspring exposed to the RF EMFs or to the F2 o...
Thus, under the conditions of the present experiment, simultaneous whole-body exposure to eight different communication signal EMFs at frequencies between 800 MHz and 5.2 GHz did not show any adverse effects on pregnancy or on the development of rats.
