Researchers modeled electromagnetic wave heating in conducting spheres representing human heads of different sizes. They found that 10-cm radius spheres (adult heads) showed only surface heating above 1000 MHz, while smaller 4-cm spheres (child-sized heads) developed dangerous internal hot spots between 250-2800 MHz. This suggests children may face greater internal heating risks from radio frequency radiation.
