Abstract:
1. A method for monitoring radio frequency energy emission by a radio frequency apparatus comprising the steps of: emitting radio frequency pulses from a radio frequency apparatus respectively at temporal intervals, each radio frequency pulse having a radio frequency power and an effective factor associated therewith; for each of said radio frequency pulses, obtaining a measurement value representing the radio frequency power of the respective radio frequency pulse at temporal intervals, by determining an exposure value for each radio frequency pulse by multiplying the measurement value for that radio frequency pulse by the effective factor for that radio frequency pulse; for each of said radio frequency pulses, electronically calculating an exposure value from said measurement value, representing a physiological effect of that radio frequency pulse on a subject exposed to that radio frequency pulse; electronically calculating an exposure-monitoring value based on a plurality of said exposure values; and limiting functioning of said radio frequency apparatus if said exposure-monitoring value equals or exceeds an exposure limit value.
