A. The smart meters we're installing emit a low level of RF and only transmit data for a few seconds per hour. The average RF levels are far below the safety standards specified by the Federal Communications Commission (FCC). The FCC is required by the National Environmental Policy Act of 1969, to evaluate the effect of emissions from FCC-regulated transmitters on the quality of the human environment. Tampa Electric only uses FCC-compliant meters.
