This reduction was accomplished by considering only those entries that were deemed to more » be of direct interest, and by using several comprehensive and detailed reviews to guide the selection process.
Approximately 50 of these entries were selected by the authors of this update for in-depth consideration. Some 2000 new entries of both publications and research programs in progress have been identified through a computer-aided literature search. The literature published prior to that date was reviewed as a part of a previous state-of-the-art review and program plan (EPRI RP-381-1). The objective of this project was to collect and review the literature which has become available since mid-1974 on the subject of biological effects of power frequency electric fields. However, further research is still needed in order to understand the nature and extent of any effects that could be = , The general findings of this update confirm the conclusion of the 1975 review that it is highly improbable that electric fields from transmission lines have any significant biological effects on healthy individuals who encounter such fields in a normal way under ordinary conditions. This reduction was accomplished by considering only those entries that were deemed to be of direct interest, and by using several comprehensive and detailed reviews to guide the selection process.
