Textbook Question
Chapter 23, Problem 83PP
The ICNIRP also has guidelines for magnetic-field exposure for the general public. In the frequency range of 25 Hz to 3 kHz, this guideline states that the maximum allowed magnetic-field amplitude is 5/f T, where f is the frequency in kHz. Which is a more stringent limit on allowable
- A. The magnetic-field guideline, because at a given frequency the allowed magnetic field is smaller than the allowed electric field.
- B. The electric-field guideline, because at a given frequency the allowed intensity calculated from the electric-field guideline is smaller.
- C. It depends on the particular frequency chosen (both guidelines are frequency dependent).
- D. Neither—for any given frequency, the guidelines represent the same electromagnetic-wave intensity.
