Are the exposure limits for portable transmitters (e.g. cell phones) and antenna towers the same?
The exposure limits for portable transmitters (e.g. cell phones) and antenna towers are different because of different exposure conditions. Portable transmitters are normally used in close proximity to the body and result in partial body exposures. On the other hand, antenna towers are located at far distances from the body, and thus RF fields from them give rise to whole-body exposure.
