Lack of effect of weak low frequency electromagnetic fields on chick embryogenesis.
Fertilised chicken eggs were incubated for 48 hours while exposed to pulsed trains of square wave magnetic fields having a duration of 0.5 msec and pulse repetition rates of 100 or 1000 Hz at magnetic field flux densities of 1.2 and 12 mu T. After exposure the embryos were scored blind for eight different gross structural features: primary vesicles, anterior neuropore, optic vesicles, auditory pits, truncal nervous system, heart, somites and blood vessels. There were no differences between exposed, sham-exposed and control eggs.
