BYNUM, James Arthur · 1936
Researchers exposed 24 male university students to 1000 MHz microwave radiation at 10 mW/cm² while they performed memory tasks involving nonsense syllables. The study found no significant differences in learning or recall ability between students exposed to the radiation and those who weren't. This suggests that short-term exposure to this specific frequency and power level doesn't impair verbal memory function.
