BIOLOGICAL EFFECTS OF RADIO FREQUENCY WAVES
No Effects Found
James C. Lin, John C. Nelson, Merlin E. Ekstrom · 1979
Long-term 148 MHz exposure at 0.5 mW/cm² showed no detectable health effects in mice across multiple biological parameters.
Plain English Summary
Summary written for general audiences
Researchers exposed newborn mice to 148 MHz radio frequency radiation for one hour daily over 10 weeks, then monitored them for nearly two years. The study found no differences in blood parameters, body weight, or disease rates between exposed and control animals at the power levels tested.

}Quick Questions About This Study
No significant effects were found on body weight, blood parameters, or disease development in mice exposed to 148 MHz radiation from infancy through adulthood at 0.5 mW/cm² power levels.
Researchers followed the mice for nearly two years after the 10-week exposure period ended, conducting blood tests and tissue examinations at multiple time points up to 600 days of age.
The mice were exposed to 148 MHz radiation at 0.5 mW/cm² (63.25 V/m) for one hour daily, five days per week, which is relatively low compared to modern wireless device exposures.
No changes in blood cell formation or composition were detected in mice exposed to 148 MHz radiation, based on regular blood draws and analysis throughout the nearly two-year study period.
The study found no significant differences in disease onset, incidence, or type between RF-exposed and control mice during necropsy and tissue examinations performed throughout the study period.
