While much attention has been given to ionizing electromagnetic stimuli which causes blatant and unalterable changes in biological systems, relatively little research has been concerned with those electromagnetic signals whose frequencies overlap with time-varying processes in living organisms. Extremely low frequency (ELF) electromagnetic fields can occur as waves between about I Hz to 100 Hz or as short pulses within this range of very low frequency (VLF) and higher frequency sources. The natural occurrence of ELF signals is associated with weather changes, solar disturbances and geophysical- ionospheric perturbations. Man-made sources have also been reported. Certain physical properties of ELF signals make them excellent candidates for biologically important stimuli. Unlike many other weather components, ELF signals have the capacity to penetrate structures which house living organ- isms. ELF wave configurations allow long distance propaga- tional capacities without appreciable attenuation of inten- sity, thus making them | | 出版日期 | Book 1974 | | 關(guān)鍵詞 | attention; nature; research; science | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4684-9004-6 | | isbn_softcover | 978-1-4684-9006-0 | | isbn_ebook | 978-1-4684-9004-6 | | copyright | Springer Science+Business Media New York 1974 |
