If you're concerned about invisible radiation from your home electronics, use the CellSensor to detect and avoid EMF sources.

While the jury is still out on the possible health effects of electromagnetic fields, you can map out high-EMF sources in your home and take steps to avoid them right now. This detector measures both radio frequency (RF) radiation (like from cell phones) and extremely low-frequency electromagnetic fields (ELF EMFs). Includes remote ELF EMF probe. Requires 9V battery, not included.
