Power‐line radiation affects Earth's magnetosphere Available to Purchase

Electromagnetic radiation from the Canadian power system is entering the Earth's magnetosphere, according to a recent report¹ in the Journal of Geophysical Research. The authors, a team from the Stanford Radioscience Laboratory headed by Robert Helliwell, have also found evidence that these power‐line emissions are amplified within the magnetosphere and cause the precipitation of electrons from it. Further studies of these phenomena, including satellite experiments, are under way.
