Effects of 2.6-4.0 GHz Microwave Radiation on E-Coli B
J. C. Corelli, R. J. Gutmann, S. Kohazi, J. Levy · 1977
E. coli bacteria showed no damage from 2.6-4.0 GHz microwave exposure, but bacterial studies don't predict human health effects.
Plain English Summary
Researchers exposed E. coli bacteria to microwave radiation at frequencies between 2.6-4.0 GHz for 10-12 hours at power levels of 20 mW/cm². They found no effects on the bacteria's ability to form colonies or changes in their molecular structure. This suggests these particular microwave frequencies at this power level don't damage this strain of bacteria.
Finding
At absorbed power levels of 20 mW in 1 ml of cellular suspensions (i.e., a specific absorption rate of 20 W/kg) for 10-12 hour exposures, no effects were observed on either the molecular structure or the CFA for this particular strain of E. coli.
