The potential for power frequency magnetic fields to enhance neoplastic
transformation has been investigated in vitro using promotion-sensitive
mouse epidermal JB6 cells. In a soft agar assay, 60-Hz magnetic fields of
0.01, 0.1, 1.0, or 1.1 mT flux density did not induce anchorage-
independent growth. In addition, these magnetic fields did not enhance
tumor promoter-induced transformation showing no increase in the maximum
number of transformed colonies and no shift in the dose- response curve.
Thus, these data do not support the notion that environmental exposures to
magnetic fields contribute to transformation.
