A possible mechanism for the effects of electromagnetic fields on biological cells

It is widely believed that electromagnetic fields can affect biological systems, including man, although the evidence remains equivocal. Quite apart from the difficulty in establishing a causal relationship, the research field has been held up by a lack of a general mechanism to rationalize why such effects might be expected. Yet, at the same time, it is weil established that even very small fields can affect checmical reactions in a way that is completely understood. Here, we attempt to explain how, to suggest some possible relevances to the biological situation, and to predict what effects might be looked for to confirm the relevance of the mechanism there. This may help to target epidemiological studies on human systems so as to establish the perceived effects.
