The effects of radiofrequency radiation on the nervous system, behavior, and the eye, and such indirect biological effects as cardiac pacemaker interference are discussed in terms of their impact on setting appropriate personnel exposure criteria for operational RF emitters.
Of primary importance is the recognition that radiofrequency (10 kHz - 300 GHz) radiation insult to man is strongly frequency dependent. Thus, all bioeffects data generated in the laboratory using smaller animals must be carefully scaled/extrapolated to equivalent effects on man before meaningful exposure standards can be established. This frequency dependent concept is reflected in United States Air Force Regulation 161-42, which establishes a 50 mW/sq cm permissible exposure limit (PEL) for radiofrequencies from 10 kHz to 10 MHz and retains the previously established 10 mW/sq cm PEL for radiofrequencies from 10 MHz to 300 GHz.
