There is much action, since competition means each company offers coverage in the same area. For example, there are six in eastern Massachusetts, plus another offering wireless Internet service. This includes cancer, leukemia, pregnancy risk, learning and sleeping disorders and serious damage to various cellular level processes. Activists care passionately about likely short and long-term damage caused while battles and lawsuits are permitted to stretch on. When regulation requires harm to be proved before exposure is limited, controls tend to arrive too late to prevent harm.
Some people are outraged, some desolate, to associate church steeples with such potential harm.
Yet, because the body of evidence available so far in peer-reviewed scientific literature does not constitute proof in scientific terms, few scientists I have talked to believe there are health risks. Some have no concern and consider it a bogus issue. Others would be willing to be concerned, but find no basis. A few scientists frame their concern by speaking about flaws in regulation and standard setting. Others believe the risk is in the phone handsets and not the antennas.
