Some have urged that the EMF bioeffects studies on animals cannot properly serve as a basis for evaluating human health hazards. I think this argument should be rejected entirely. The predicate for the expenditure of a large amount of public funds for EMF bioeffects research has precisely been that the model cellular and animal systems proposed by the investigators for study were biologically relevant and appropriate to support inferences involving consequences for exposed human subjects. Now that the data has been obtained, it simply cannot credibly be maintained that the mode of reasoning in which results from cells and animals are imputed to human subjects is intrinsically faulty.
