phone, the system handling your call controls the power level. This power can
range from 0.006 watts to 0.2 watts in digital mode.

In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) and the
American National Standards Institute (ANSI) joined in updating ANSI’s 1982
standard for safety levels with respect to human exposure to RF signals. More
than 120 scientists, engineers and physicians from universities, government
