EXPOSURE ASSESSMENT AND SOURCE CHARACTERIZATION Objectives The first stated objective is to gather data on the range and typical characteristics of electric and magnetic fields to which the general population and subgroups might be exposed. The purpose is to ensure that biomedical researchers are aware of the full range of exposure conditions that occur in the environment.

:D Research Agenda and Communications Plan (1994) which focuses on "Electric and Magnetic Fields Produced by the Generation, Transmission, and Use of Electric Energy," has been expanded in the implementation plan to include all ELF and ELF-modulated EMF.

Overall Concerns The exposure assessment and source characterization activity is a large undertaking burdened with significant inefficiencies as a consequence of the imposed deadlines. Because it is not known at present which aspects of EMF exposure, if any, can damage human health, a prudent measurement program requires comprehensive measurements covering a wide range of field attributes.

From page 36... ...
If the health effects research identifies adverse effects of exposure and the exposure conditions that lead to those effects, an efficient set of exposure assessment studies focusing on the field attributes of concern could be carried out relatively quickly. For example, if magnetic field transients turn out to be the exposure of concern, investigators can proceed immediately to the environments identified in the range-finding study, where transients have been found, and carry out a focused assessment of exposure to transients of the type found to be biologically active.

From page 37... ...
Despite uncertainty about the aspects of exposure that could influence human health, reduction techniques that involve avoidance or shielding are likely to be effective for most field attributes, e.g., shielding to reduce the average rms magnetic field intensity will also reduce the magnitude of the transients. The need for additional projects in this area or for continuation of the identified project beyond 1 year is to be determined based on "identified and documented needs." That criterion is vague; the committee members hope it will not lead to escalation of work in this area until some health effect of EMF exposure is established and the exposure conditions leading to that effect are defined.

Project 9, which will begin the actual collection of environmental field data, is based on a proposed protocol that places only modest emphasis on a few parameters other than broadband field intensity. It would seem more productive to progress through the measurement guideline development process of Projects 7 and 8 before proceeding with the data collection phase.

First, positive or negative results will give weight to decisions concerning whether power frequency EMF is biologically active in marrunalian cells in a manner that could contribute to adverse health effects. Second, if positive effects are identified, these data will aid in establishing hypotheses that can be tested directly in future studies.

These seven studies win produce an extremely limited amount of data. However, they are complemented by a multimillion-dollar effort to examine the effects of exposure of animals to power frequency magnetic fields.

These projects are specifically identified in the communications implementation plan and they appear to have been implemented in a timely fashion. The five remaining projects facilitate information dissemination to specific audiences; they appear to be consistent with the implementation plan.
