Welcome to episode 496 of The Whole View! This week, Dr. Sarah and Stacy look at the science of radiation in physics to determine whether or not we need to be careful around microwaves, EMFs, and 5G radiation. If you enjoy the show, please review it on iTunes! Key Takeaways Dr. Sarah did her B.Sc. in honors physics, and her Ph.D. is in medical biophysics. So, this is the perfect background to talk about how electromagnetism (physics) affects our health (biology). The root of conspiracies and myths around electromagnetic fields, from microwaves to 5G, stems from the difference between technical terms and colloquial terms, like theory and hypothesis. Even more from fear and misunderstanding of the word “radiation.” In physics, radiation more generally refers to a form of energy that travels and spreads out as it goes. Light is an example of electromagnetic radiation. Longer wavelength equals lower frequency and lower energy, and shorter wavelength means higher frequency and higher energy. Radiation can be either ionizing (carrying enough energy to liberate electrons, thus ionizing the atoms those electrons were orbiting) or non-ionizing (not having enough energy to release electrons). All longer wavelengths–ultraviolet, visible light, infra-red, microwaves, and radio-waves– are non-ionizing because […]
