The RF energy could conceivably have an effect on cell membranes and the
potentials that develop across cell membranes. Perhaps some cells are more
sensitive to such changes in membrane potentials and lead to higher incidences
of certain diseases which in this case is leukemia.

As for not noticing the correlation for over 80 years that isn't so unusual. It
really is contingent on many factors including the increase in the number of
stations over the years, the increase in power over the years, the proximity of
the population to RF over the years (ie. the shift from a rural to an urban
population), the extent of the exposure, lifestyle and dietary changes and so on
and so on. It such a case it may take quite awhile to isolate a potential
causative agent and even then it wouldn't be overwhelmingly conclusive proof.
Too many variables to take into account.

I don't doubt that high levels of RF can be dangerous. The first two chief
engineers I worked with both died of cancer in their 50s.

Maybe they got cancer from some other cause (both smoked), but I still
feel
like I'm inside a microwave oven anytime I'm around an AM transmitter
site.




Wouldn't FM broadcast antennas be an even greater concern? The height of
most adults would make them resonant somewhere near, or in, the FM broadcast
band. I'd expect energy transfer to be more effiecnt from the FM broadcast
antenna to the human body than it is in the AM broadcast band.

Anyway, there's been over 80 years of kW+ levels of AM broadcasting, and it
seems strange this leukemia concern has gone unnoticed until now.
