Researchers measured extremely low frequency (ELF) magnetic fields in welding and steel manufacturing facilities, finding exposures of 0-10 mT at 50 Hz in typical work areas, with some induction heaters producing fields up to 60 mT. The study suggests these industrial magnetic field exposures likely cause magnetophosphenes (visual light sensations) in workers, though these effects are hard to detect in brightly lit industrial environments.

Researchers demonstrated that radar transmitters operating at 1, 3, and 10 gigahertz can be directly heard by the human brain, bypassing the ears entirely. The effect occurred at energy levels considered safe for all-day exposure, suggesting the brain itself can detect electromagnetic radiation. This phenomenon may explain reports of people hearing meteors and aurora displays.

Researchers developed improved mathematical methods to calculate how radiofrequency radiation affects the human body at frequencies near and above whole-body resonance. Previous calculation methods failed at higher frequencies due to mathematical instability, limiting safety assessments. The new approach uses advanced matrix inversion techniques to extend dosimetry calculations into previously inaccessible frequency ranges.

Scientists studied how microwave radiation is absorbed by the human body using layered models that include skin, fat, and muscle tissues. They discovered that at 1.2 GHz, these body layers create a resonance effect that doubles radiation absorption compared to simpler models. This finding suggests that realistic body composition significantly affects how much electromagnetic energy we absorb from wireless devices.

Researchers measured how radiofrequency radiation is absorbed by human and animal tissue models when exposed to near-field conditions (close-range exposure) versus far-field conditions. They found that near-field exposure creates different absorption patterns and potentially dangerous "hot spots" of concentrated radiation in body tissues. This matters because most of our daily EMF exposure comes from devices held close to our bodies, like cell phones.
