What are the exposure levels from mobile phones?

RF exposure levels are directly proportional to the actual output power of a mobile phone during a call, or sending and receiving data. In everyday use, the mobile phone output power is usually significantly lower than maximum output power due to adaptive power control.

Many factors can change the output power of a mobile phone and intensity of exposure including technology, location, transit, and usage of the phone. The output power levels of mobile phones used in rural areas can be higher than in urban areas due to the greater distance to the nearest base station.

The average power inside a building can also be higher than outdoors as the building can attenuate the mobile reception. It is also quite common to have dedicated in building mobile coverage systems these days in which case mobile phones will operate at the lowest possible power.
