What are the health effects of the standards level? Is it cumulative over time like cigarettes?

There are reported no adverse health effects at exposure levels equal to or below the FCC standard.  Unlike the toxic substances in cigarette smoke or other known carcinogens, RF energy at low levels is not considered to have a cumulative effect over time.  Exposure to RF fields below the FCC public limit is allowed 24 hours a day, 7 days a week.
