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.

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.
