surveys of the health of people living near base stations
Two recent papers
report the results of surveys of the health of people living near
base stations. Santini and colleagues carried out their study in
France, and Navarro and colleagues in Murcia, Spain. Both studies
compared symptoms in those living near a base station with those
living further away. The participating subjects estimated the distances
from the base station, but Navarro's study supplemented this by
measurements of electromagnetic fields in the bedrooms of the subjects.
found that those living close to the base station reported more
symptoms than those living further away. It is possible, however,
that there was bias in each study. Santini's group solicited participants
through the media by stating that they planned to study people living
near base stations. Navarro's team delivered questionnaires to people
with the explanation that they were evaluating the impact of the
base stations. It is reasonable to assume that those living nearer
the base stations may have held stronger negative views of the stations
than those living further away, which could have led to skewed results.

damage in blood cells of phone users
India has shown an increased frequency of chromosomal abnormalities
in lymphocytes (white blood cells) of people who had used cell phones
for at least 2 years, compared with control subjects who had not
used cell phones. These types of abnormalities are thought to be
involved in the early stages of cancer. Blood samples from 24 cell
phone users were compared with samples from matched controls. The
lymphocytes were cultured and then examined by personnel who were
not aware of the source of the specimen.

reviews in Bioelectromagnetics
"Bioelectromagnetics" has published a Supplement containing
reviews of the effects of RF fields on various aspects of human
health. It is a valuable addition to the literature on the subject.
