Here are two important documents which relate leukemia to AM radio
emissions. The Korean scientific paper below, by Mina Ha was published in
the American Journal of Epidemiology, Oxford Journals.
 
The second document which is attached to this message, is the July 13, 2007
publication of Micro Wave News. This paper mentions the same Korean
research and also an interesting situation happening in the United States.
It contains valuable links to other important research and information about
the health harm caused by AM radio transmitters.

Micro Wave News is a leading publication showing harm being caused to health
and the environment by electro magnetic radiation. I highly recommend that
you visit www.microwavenews.com I thank Louis Slesin for all his continuing
efforts to bring these dangers to our attention.

Leukemia and brain cancer patients under age 15 years, along with controls
with respiratory illnesses who were matched to cases on age, sex, and year
of diagnosis (1993-1999), were selected from 14 South Korean hospitals
using the South Korean Medical Insurance Data System. Diagnoses were confirmed
through the South Korean National Cancer Registry. Residential addresses
were obtained from medical records. A newly developed prediction program
incorporating a geographic information system that was modified by the
results of actual measurements was used to estimate radio-frequency
radiation (RFR) exposure from 31 amplitude modulation (AM) radio
transmitters with a power of 20 kW or more. A total of 1,928 leukemia
patients, 956 brain cancer patients, and 3,082 controls were analyzed.
Cancer risks were estimated using conditional logistic regression adjusted
for residential area, socioeconomic status, and community population
density. The odds ratio for all types of leukemia was 2.15 (95% confidence
interval (CI): 1.00, 4.67) among children who resided within 2 km of the
nearest AM radio transmitter as compared with those resided more than 20
km from it. For total RFR exposure from all transmitters, odds ratios for
lymphocytic leukemia were 1.39 (95% CI: 1.04, 1.86) and 1.59 (95% CI:
1.19, 2.11) for children in the second and third quartiles, respectively, versus
the lowest quartile. Brain cancer and infantile cancer were not associated
with AM RFR.
