[Risk from electric current greater than assumed].
Despite its importance for the assessment of the effects of electric current and for technical safety considerations, not only does the electric perception threshold remain uncertain, but essential questions are still unanswered and contradictions unresolved. Via measurements at 908 persons randomly selected from the general population, including 708 adults (349 men, 359 women aged between 16 and 60 years), the problems of extrapolation to the general population and adequate statistical representation have now been overcome for the first time. The results show that existing assumptions about electric current perception need to be drastically corrected. It has been shown that the assumed electric perception threshold has been too high by a factor of 10, and that women are substantially more sensitive than men. This means that present gender-specific differences in electrosensitivity need revising. On the basis of the evidence of significant underestimation of the reaction variability in the general population, present assumptions on safety limits and safety factors urgently need to be reviewed. By no means can a relaxation of safety regulations be justified.
