Research relevant to EMF exposure in children - baby monitors, tablets, school WiFi, and wearables.
## Children's EMF Exposure: Understanding the Unique Risks Children face a fundamentally different EMF landscape than adults. Their developing nervous systems absorb radiation at rates up to 10 times higher than adult brains, according to research from France's National Frequency Agency. Yet the devices surrounding our kids today - from baby monitors broadcasting all night to tablets held inches from developing brains - weren't designed with children's unique vulnerabilities in mind.
