Electromagnetic exposures do not produce tissue effects in a linear way. Many of our normal physiologic functions behave in nonlinear ways, and our environmental EMF exposures are multiple and complex. Our tissues respond only to certain frequencies, or certain intensities -- or a number of related factors -- in some conditions but not others.
Unlike testing for the adverse effects of a substance, where our responses may (but don't always) depend on the amount of exposure or bioaccumulation, the effects of exposure(s) to EM fields -- on some measurable parameters -- is not simply "dose-related".
Policy-making on issues of personal health and community safety does not account for these real effects.
The mechanisms responsible for the nonlinear effects are unknown, according to Dr. Blackman. The biological responses more closely resemble responses to a chemical combination of varying ingredients than to a single substance.
