Radiation and electromagnetic fields from cellphones can be dangerous. Plus, electromagnetic fields usually mean there’s a ghost around too, so it’s good to know when there might be one around you. Some say EMF is safe, others say it’s really dangerous. Why take the chance, when you can conduct your own research with this handheld EMF detector.
It will measure radio frequency radiation and extremely low-frequency magnetic fields and should be able to tell you which electronics in your home are the worst offenders. And if you get a reading where there are no electronics, then you probably have a ghost, in which case you’ll want to make like Scooby and Shaggy and get the hell out as quick as you can.
