An examination of regenerating hepatic tissue subjected to radio-frequency irradiation
No Effects Found
Byron D. McLees, E. D. Finch, M. L. Albright · 1972
1972 study found no liver cell damage from 13.12 MHz radiation, but modern devices operate at much higher frequencies.
Plain English Summary
Summary written for general audiences
Researchers exposed regenerating rat liver tissue to 13.12 MHz radio frequency radiation to study cellular damage and chromosomal effects. They found no evidence of cellular damage at either the microscopic or ultrastructural level. The study also established the power threshold needed to raise the animals' body temperature.

}Quick Questions About This Study
Researchers used 13.12 MHz radio frequency radiation, which falls in the shortwave radio band. This frequency is much lower than modern cell phones (800-2100 MHz) and WiFi networks (2.4-5 GHz).
No, researchers found no evidence of cellular damage at either the microscopic or ultrastructural level in regenerating rat liver tissue exposed to 13.12 MHz radiation.
Cell phone radiation operates at 800-2100 MHz, which is 60-160 times higher frequency than the 13.12 MHz tested in this liver study. Higher frequencies can have different biological effects.
The study determined the threshold power level needed to elevate rats' body temperature during 13.12 MHz exposure, though specific power values weren't detailed in the available abstract.
No, the researchers investigated chromosomal aberrations in regenerating rat liver tissue but found no evidence of chromosomal damage from 13.12 MHz radio frequency radiation exposure.
