What is the maximum exposure limit for microwave energy in mW per centimeter under U.S. Health Department regulations?

Microwave exposure limits are set to prevent tissue heating, so the limit is expressed as a maximum permissible exposure in terms of how much power per unit area a person can be exposed to. In typical U.S. health regulation references used for this topic, the allowable level for microwave energy is given as about 5 milliwatts per centimeter. That is why the correct choice is the value 5.0. The smaller figures would represent exposures far below the standard regulatory limit, and thus are not the limit commonly cited in this context.
