Development of chicken embryos following exposure to 60‐Hz magnetic fields with differing waveforms

摘要

AbstractPrevious studies in my laboratory have revealed a reproducible and statistically significant increase in the number of malformations in live chicken embryos that had been exposed during the first 48 h of incubation to a pulsed magnetic field (unipolar pulses, 100‐pps, 1‐μT peak density). In marked contrast, no adverse effect was seen following similar exposure to 60‐Hz, bipolar, unipolar, or split‐sine waves at 3‐μT peak‐to‐peak. In the four experiments comprising the present study, differences in the numbers of malformations between control and experimental groups were not statistically significant. Field‐free incubation for an additional 72 h after exposure to a bipolar sine wave for 48 h resulted in anincreasein normal live embryos in both control and treated groups. © 19
