FCC: Microwave News Article Archive (2004 - )

The Centers for Disease Control and Prevention —CDC— is the first U.S. health agency to call for precaution in the use of cell phones.

But not for long. As soon as word of the CDC’s new outlook spread, the precautionary advice was withdrawn. Our original story is below, followed by an August 20 addendum.

“Along with many organizations worldwide, we recommend caution in cell phone use,” the CDC stated on its Web site’s FAQ About Cell Phones and Your Health and followed up with a call for more research to answer the unresolved cancer question.

The Federal Communications Commis- sion (FCC) has never levied a fine against a cell phone company for exceeding its RF exposure limits from a base station antenna.

That's not because all of the 300,000 cell sites in the U.S. comply with the FCC rules, according to an Industry Insider with years of training and experience measuring RF radiation. He told us that he has found RF levels higher than those allowed under the FCC rules at sites across the country. The real reason there have been no fines, he said, is "because there's collusion between the companies and the government." The insider, an RF engineer, calls himself "EMF Expert"; he asked that his real name not be used.

"The carriers and the FCC have an extremely cozy relationship," said the engineer. "Whenever there's a problem, someone in the FCC's RF safety office warns the carrier and the company then puts the 'fire' out."

Bloomberg News caught a lot of people by surprise last Friday morning with a story announcing that the Federal Communications Commission (FCC) would review its rules on radiation exposures from cell phones. As  Bloomberg's Todd Shields pointed out, the move was long overdue: The FCC's current exposure standard was set in 1996.

Just as interesting is a question no one seems to be asking: Why was this in the news?

There are many reasons not to use a cell phone in an elevator. The most obvious would be as a courtesy to other passengers. Another is that a phone has to work harder in a shielded space. It's forced to operate at higher power levels for the signal to get out and reach the nearest tower and that leads to more ambient radiation in the elevator.

What most cell phone users would never consider is that a fellow passenger absorbs some of the radiation that would otherwise bounce back off the walls. It turns out, according to some new calculations from Japan, that a lone user can get a maximum exposure of about 1.6 W/Kg, 80% of the ICNIRP standard (2 W/Kg). But be advised that exposures could exceed the current U.S. FCC standard by a wide margin, under worst-case conditions. (This is a rare —no, unique— example of an American EMF standard being stricter than those in other countries.) The FCC limit is averaged over only 1g of tissue and, as Jim Lin, a member of ICNIRP, has often pointed out, increasing the averaging volume from 1 g to 10 g could triple the allowable radiation exposure (see MWN, N/D00, p.3). These new findings appear in the May issue of the IEEE Transactions on Microwave Theory and Techniques.
