Recent research reports appear to indicate a real possibility that the
low-frequency electromagnetic field produced by the power transmissio
n and distribution network presents a health problem. A critical asses
sment of the available information is presented here. The state of kno
wledge, available evidence and conflicting reports indicate a definite
need for interim action by the power industry. New direction for anal
ytical research, possible interim avoidance measures, proper advice to
clients and the public are discussed. Detailed mathematical modeling
for the linear and nonlinear dynamics of DNA and the chromosome as a w
hole is suggested.
