Understanding Radio Frequency
According to the Federal Communications Commission (FCC):
Radio waves and microwaves emitted by transmitting antennas are one form of electromagnetic energy.
They are collectively referred to as radiofrequency or RF energy or radiation.
(Note that the term radiation does not mean radioactive.)
Based on years of studying whether radio waves cause health effects, the FCC has adopted Maximum Permissible Exposure (MPE) limits for radio transmitters of all types, including radio-read transmitters like those used on our Neptune water meters.
It includes a prudent margin of safety just in case some health effects are too subtle to have been detected. Radio-read transmitters operate far below the FCC limit.
For more information and understanding radio frequency and the electromagnetic fields they generate, please see the FCC and other agency links below.
For more information on whether these devices interfere with pacemakers and other medical devices, please read the FDA statement Interference with Pacemakers and Other Medical Devices.
