Is AM Radio Harmful?
By Stephen Leahy
Aug. 16, 2004 Korean scientists have found that regions near AM radio-broadcasting towers had 70 percent more leukemia deaths than those without. The study, to be published in an upcoming issue of the International Archives of Occupational and Environmental Health, also found that cancer deaths were 29 percent higher near such transmitters. .. Two years ago an Italian study found death rates from leukemia increased dramatically for residents living within two miles of Vatican Radio's powerful array of transmitters in Rome. The Koreans looked at the death rates in 10 regions with AM radio-transmitting towers broadcasting at more than 100 kilowatts and compared them with control areas without transmitters. The substantially higher cancer mortality in those who lived within two kilometers of the towers led researchers to conclude that more investigation was needed. However, they also said their study did not prove a direct link between cancer and the transmitters. "There have been many studies like these, and they aren't very convincing," said Mary McBride, an epidemiologist at the British Columbia Cancer Agency. Many other factors could have contributed to those cancer rates, said McBride, who has headed a number of similar studies and found no direct link. Equally important is that studies in the lab don't show how radio waves can produce cancers, she said. Debate continues over the health effects of radio waves from transmitters, both large and small, and other forms of electromagnetic fields, including power lines and microwaves. Sam Milham, a Seattle-based epidemiologist and a pioneer in electromagnetic-field research, is convinced there are health effects. "Lots of research papers from around the world show increased cancers near transmitters, although TV and FM transmitters are more often implicated." Moreover, many lab studies show low-frequency EMF disrupt living cells, Milham asserts. Critics like McBride say such results are often difficult to reproduce at other labs. Milham says that's because of differences in the Earth's magnetic field and stray EMF. In an attempt to settle some of this, California's Department of Health Services reviewed all the current studies of EMF risks from power lines, wiring and appliances in 2002. It found no conclusive evidence of harm. However, links to childhood leukemia, adult brain cancer and Lou Gehrig's disease could not be ruled out. "I'm convinced that politics and corporate interests are behind denials (that say) there are no health effects," said Milham. Meanwhile, the FDA and the World Health Organization are urging more studies, especially of radio waves from cell phones. http://www.wired.com/news/medtech/0,...tml?tw=rss.TOP (See also related stories at the website). |

Did anybody check for PCBs and (other) known chemical carcinogens in the environment? the Italian study: ONE transmitter, near Rome. that's a statistical sample? you could probably prove lasagna causes baldness with those techniques |

Did anybody check for PCBs and (other) known chemical carcinogens in the environment? Good stuff! We used to have the power company crews pour used PCB oil on our access roads. Really kept the dust down. Back then, nobody thought anything that came in drums marked "SAFETY OIL" would turn out to be unsafe. Probably all the lead contamination in the groundwater from our sweated- connection radials didn't help either. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

This was pretty much the case for the rural roads through a lot of the state. And definitely it was the case for all of the power line right of way roads. Not an uncommon thing at all, and sadly the contamination will outlast all of us. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Too much of Rush can be harmful, too.

Maybe the areas around transmitters are clear of trees. You get a lot more absorption of sunlight on your body than of any AM signal, which is much lower in frequency. Also, sunlight is a demonstrated cancer risk. Better stay in the dark. |
