There exist various standards for the safety limits of human exposure to electromagnetic radiation. one of them is the ieee standard, whose recommendations for the maximum permissible time-average intensity of the poynting vector in uncontrolled environments (where individuals generally have no knowledge or control of their exposure to em fields) at frequencies between 100 mhz and 300 ghz are as follows: (i) pavg, max=2 w/m2 for 100 mhz ≤ f < 300 mhz, (ii) pavg, max= f/150 w/(mhz m2 ) for 300 mhz ≤ f < 15 ghz,(iii) and pavg, max=100 w/m2 for 15 ghz ≤ f < 300 ghz. based on this standard, compute the maximum permissible levels for the rms intensities of the electric and magnetic fields in air at frequencies of 150 mhz, 1.5 ghz, and 15 ghz respectively. note: ⃗ = || 2 = |�
