The literature raises serious concerns regarding the levels of radio frequency (3 kilohertz to 300 gigaherts) or extremely low frequency (300 hertz) exposures produced by 'smart meters' to warrant an immediate and complete moratorium on their use and deployment until further study can be performed," the academy asserts.
