Your wireless phone is a radio transmitter and receiver. It is designed
and manufactured not to exceed the exposure limits for Radio
Frequency (RF) energy set by the Federal Communications
Commission (FCC) of the U.S. Government.

These FCC RF exposure limits are derived from the
recommendations of two expert organizations: the National Council
on Radiation Protection and Measurement (NCRP) and the Institute of
Electrical and Electronics Engineers (IEEE). In both cases, the
recommendations were developed by scientific and engineering
experts drawn from industry, government, and academia after
extensive reviews of the scientific literature related to the biological
effects of RF energy.
