Weak
GSM and third generation EM fields may affect brain function
A recent report
from the Netherlands Organisation for Applied Scientific Research
(TNO) described a research study that examined the relationship
between electromagnetic fields, subjective complaints, and cognitive
function. The EM fields included GSM and UTMS-like fields. The latter
are the fields from "third generation" mobile phones.
The authors of the study report that EM fields such as those from
base station antennas may be associated with changes in well being
and in cognitive function, when compared with baseline tests. For
more, see "Research -
Clinical experiments - cognitive function".

Cataracts
and electromagnetic radiation
In his latest
column in the September 2003 issue of Radio Science Bulletin, James
Lin reviews studies that have examined the induction of cataracts
of the lens of the eye by electromagnetic radiation. He discusses
experiments in rabbits and in rhesus monkeys and points out that
microwaves produce cataracts in these animals only at high SARs,
associated with a temperature increase in the eye. Lin then reviews
the situation in humans and concludes:
"However,
linear extrapolations of computed results indicate that the incident
density required for the human eye to reach the cataractogenic
threshold may be only slightly lower than that needed for rabbits.
Thus, any concern for microwave radiation, within the exposure
guidelines, inducing cataracts in humans may be exaggerated".
