reviews of mobile phones and cancer
There have been
two recent reviews of the scientific literature on the subject of
radio frequency energy and cell phones. One by Jauchem is an update
of a previous review and covers the period from mid-1998 through
2002. He concludes:
evidence for any proven health effects (involving brain tumours
and malignancies, leukemia, other cancers, and the central nervous
system) of low-level radiofrequency energy exposure is minimal".
The other review,
by Kundi, concentrates on epidemiological studies of cell phones
and cancer. He reviews the difficulties encountered in performing
these studies and makes recommendations for future research. He
also briefly reviews animal and in vitro studies. His overall conclusions
differ somewhat from those of Jauchem. He says:
epidemiological studies approaching meaningful latencies found
evidence for an increase cancer risk and because there is corroborating
evidence from at least one animal experiment and from other experimental
and in vitro and in vivo studies, the fundamental pessimism of
environmental hygiene forces the recommendation of caution and
introduction of protective measures that are easily implemented".

aspects of the use of cell phones
of our web site do not include the monitoring of safety aspects
of cell phones, and does not review articles about cell phone use
while driving a car. We recently discovered an article whose main
emphasis is on these issues. However, we include reference to it
in this month's "What's New" because it is a useful review
of general aspects of cell phones, including health and legal issues.
The situation in the USA is the focus, but the article will be of
interest to readers from other countries.

effect of an electromagnetic field and the shape of a cell
colleagues have studied the internal field distribution in human
red blood cells exposed to microwave radiation at 900 MHz. They
found that the interaction of the field with the cell is influenced
by the electrical properties of the membrane and cytoplasm of the
cell, and by its shape. They point out that a realistic shape should
be used in calculations of the electrical response of cells.
