Rat embryos showed no developmental harm from RF exposure up to 5.0 W/kg, levels exceeding typical cell phone emissions.

Plain English Summary

Summary written for general audiences

German researchers exposed developing rat embryos to radio frequency electromagnetic fields at various power levels for up to 36 hours to test whether EMF exposure during critical development stages causes birth defects or growth problems. The study found no significant effects on embryo development, growth, or cellular structure across all tested exposure levels, including levels far exceeding typical telecommunication device emissions. This suggests that RF fields at these intensities may not pose developmental risks during embryonic growth.

Study Details

The aim of this study is to investigate The lack of effects of nonthermal RF electromagnetic fields on the development of rat embryos grown in culture.

Rat embryos (9.5 days old) were exposed for up to 36 h to various radio frequency (RF) electric and ...

All these data have been taken as sets of different intermediate frequency (IF) amplitude modulation...
