General exam question G0A02
Subelement G0, ELECTRICAL AND RF SAFETY· Group G0A
Which of the following is used to determine RF exposure from a transmitted signal?
- A.Its duty cycle
- B.Its frequency
- C.Its power density
- D.All these choices are correct (correct answer)
WhyA transmitted signal's RF exposure is determined by its duty cycle, its frequency, and its power density. A transmitted signal's RF exposure depends on its duty cycle (how much of the time it's actually transmitting), its frequency (the body absorbs different frequencies differently), and its power density at the point being evaluated, all three feed directly into the exposure calculation, answer D. Since A, B, and C are each a real factor the evaluation depends on, the complete answer has to include all of them.
