The U.S. Air Force is concerned with the health and safety of personne
l working with emitters of nonionizing electromagnetic radiation. Ther
efore, an understanding of basic mechanisms of interaction of this rad
iation with biosystems is essential. A non-resonance, nonclassical mec
hanism exists for interactions with biosystems under low energy (isoth
ermal) field conditions. This mechanism is slow, or delayed, luminesce
nce. Such a mechanism can form the basis for very sensitive biosensors
naturally or artificially connected to metabolic and synthetic cellul
ar processes.
