Abstract
This talk describes experimental results which prove that microwaves can interact with biological cells in a nonthermal manner. It is shown that observed microwave effects differ strongly from those obtained by applying other Types of energy instead of microwaves at equivalent rates. The two most intriguing aspects of the interaction are that there exists an intensity threshold above which the effects appear, and that the effects are different for minute changes of microwave frequency. A step-like intensity dependence is paired with a resonant frequency dependence. The latter is described by a quality factor of about 104. The effects are as yet unexplained. The locus of interaction is not known. It is however remarkable that both an intensity threshold and a resonant behaviour are predicted in H. Frohlich’s hypotheses of coherent excitations in biology.

With regard to microwave safety driving public anxieties (P. Brodeur, The Zapping of America, Norton, New York, 1977) from a scientiffically weak basis, this probably hinders the advancement of science. Thus, such an emotional atmosphere generates preconcpetions and may even lead to attempts to “prove” the nonexistence of any nonthermal biological microwave effects.
