See for example E.L. Carstensen and E.L Sevier: Biological Effects of Transmission Line Fields, New York, 1987; K. Foster: Weak magnetic fields: cancer connection?, In: Phantom Risk, K. Foster, D. Bernstein & P. Huber, Eds., MIT Press, 1993; W.R. Bennett: Cancer and powerlines, Phys. Today 47:23-29, 1994; T.S. Tenforde and W.T. Kaune: Interaction of extremely low frequency electric and magnetic fields with humans, Health Phys. 53:585-606, 1987; R.K. Adair: Constraints on biological efects of weak extremely-low-frequency electromagnetic fields, Phys. Rev. A43:1039-1048, 1991.
Schwan's conclusion seems broadly acceptable to professional physicists. For example, in 1995, the Board of Councillors of the American Physical Society voted 35:1 to issue a press release saying that powerline EMFs do not affect human health.
Not all physicists agree with Schwan's calculations and assumptions. There have been many attempts to explicate EMF-induced bioeffects on the basis of different assumptions. See for example A.R. Liboff: Cyclotron resonance in membrane transport, In: Interactions Between Electromagnetic Fields and Cells, A. Chiabrera, C. Nicolini and H.P. Schwan, Eds., Plenum, New York, pp. 281-2956, 1985; F.S.
