AN EXAMINATION OF REGENERATING HEPATIC TISSUE FOLLOWING IN VIVO EXPOSURE TO R.F. RADIATION

Byron D. McLees, Edward D. Finch, Marion L. Albright · 1971

Researchers exposed male rats to 13.12 MHz radio frequency radiation for up to 44 hours after liver surgery to test for genetic damage during tissue regeneration.
