Proflavin and microwave radiation: absence of a mutagenic interaction.
Meltz ML, Eagan P, Erwin DN · 1990
Researchers exposed mouse leukemic cells to 2.45-GHz microwave radiation (the same frequency as microwave ovens) at high power levels while simultaneously treating them with proflavin, a DNA-damaging drug. They found no evidence that the microwave radiation enhanced the drug's ability to cause genetic mutations, nor did the radiation alone cause any DNA damage. This suggests that microwave radiation at these levels does not interact with chemical mutagens to worsen genetic damage.
