RF animal studies: Microwave News Article Archive (2004 - )

Senior managers at the National Toxicology Program (NTP) released the preliminary results of their cell phone radiation study late last week. They were so concerned about the elevated rates of two types of cancer among exposed rats that they felt an immediate public alert was warranted. They considered it unwise to wait for the results to wend their way into a journal sometime next year. Not surprisingly, the NTP report generated worldwide media attention.

There were some startling reactions. Both the American Cancer Society (ACS) and Consumer Reports immediately shelved their long-held, wait-and-see positions. In a statement issued soon after the NTP’s press conference, Otis Brawley, ACS’ chief medical officer, called the NTP report “good science.” Consumer Reports said that the new study was “groundbreaking” and encouraged people to take simple precautions to limit their exposures.

However, much of the mainstream media saw it very differently. The Washington Post ran its story under the headline, “Do Cell Phones Cause Cancer? Don’t Believe the Hype.”

The cell phone cancer controversy will never be the same again.

The U.S. National Toxicology Program (NTP) is expected to issue a public announcement that cell phone radiation presents a cancer risk for humans. The move comes soon after its recently completed study showed statistically significant increases in cancer among rats that had been exposed to GSM or CDMA signals for two-years.

Discussions are currently underway among federal agencies on how to inform the public about the new findings. NTP senior managers believe that these results should be released as soon as possible because just about everyone is exposed to wireless radiation all the time and therefore everyone is potentially at risk.

The RF–cancer story took a remarkable turn a few days ago. A new animal study challenged many of the assumptions which lie at the heart of claims that RF radiation —whether from cell phones, cell towers or Wi-Fi— are safe.

The new study, from Germany, a replication of an earlier experiment, also from Germany, found that weak cell phone signals can promote the growth of tumors in mice. It used radiation levels that do not cause heating and are well below current safety standards. Complicating matters even further, lower doses were often found to be more effective tumor promoters than higher levels; in effect, turning the conventional concept of a linear dose-response on its head.

The National Institute of Environmental Health Sciences (NIEHS) is negotiating a sole source contract with the IIT Research Institute (IITRI) in Chicago to run the National Toxicology Program’s (NTP) RF–animal studies. The studies will cost in excess of $10 million. The NIEHS requested proposals last February, but no one responded.
