The video explores the radiation emitted by smartphones and other wireless devices, focusing on electromagnetic radiation. It explains the difference between non-ionizing and ionizing radiation, highlighting that smartphones emit non-ionizing radio waves, which are generally considered safe. However, ongoing research examines potential health effects from prolonged exposure. The video suggests practical strategies to reduce radiation exposure, such as using airplane mode, turning off Wi-Fi when not needed, and keeping phones away from the body.
