An old analog hand-held cellular telephone operates in the 860 to 900 MHz band and has a power output of 0.600 W from an antenna 10.0 cm long.

a. Find the average magnitude of the Poynting vector 4.00 cm from the antenna, at the location of a typical person's head. Assume that the antenna emits energy with cylindrical wave fronts. (The actual antenna pattern is much more complicated) The cylindrical waves fall off with distance S ∞1/R.

b. The ANSI/IEEE C95.1-1991 maximum exposure standard is 0.57 mW/cm^2 for people living near cellular telephone base stations would be continuously exposed to the radiation. Compare the answer in part A to the standard.
