ABSTRACT
Reports of biological effects of low-level electric and magnetic effects have been generated with emphasis on one or more of the multiple branches of the sciences involved in bioelectromagnetics. This chapter explores the notion that traditional practice of electric and magnetic field exposure effects assessment is based on spatio-temporal models built on approximations of physical, chemical, and biological experimental aspects which may obscure details with the potential to introduce substantial experimental variations. It focuses on in vitro and low-level Extremely Low Frequency exposures, and details its conclusions and recommendations to exposures on other ranges of the electromagnetic spectrum accordingly. With the exception of experimentation with static magnetic fields, induced electric fields will always appear in the wet culture container, with their magnitude, frequency, and spatial orientation depending on the specific factors involved. The necessity for uncertainty and variability determination, validation, quality assurance, and sensitivity analysis as a means to assess causality needs to be understood and applied.
