WHO handbook on risk communication
The World Health
Organization published a new handbook in October 2002, "Establishing
a dialogue on risks from electromagnetic fields". The WHO states:
"The handbook is intended to support decision-makers faced
with a combination of public controversy, scientific uncertainty,
and the need to operate existing facilities and/or the requirement
to site new facilities appropriately". The publication can
be downloaded from the WHO EMF site www.int/peh-emf
effect of EMF on rats' spatial learning
colleagues studied rats using a system that exposed only the rats'
heads to 900 MHz electromagnetic fields, pulsed at 217 Hz. The SARs
were 1 and 3.5 w/kg in different tests. The exposed animals were
compared to sham-exposed and cage-control rats. After 45 minutes
exposure the rats performed two tasks - an elimination task in a
radial-arm maze, and a spatial navigation task. There were no differences
between the various groups in the performance of these tasks. For
more details, see "Research
- Toxicological experiments - brain function".

exposure to GSM-900 electromagnetic fields affect the performance
of rats in spatial learning tasks? Behavioural Brain Research 129:202-210.
Another study shows faster brain function with
cell phone exposure
In "Research - Clinical
- cognitive function", we discuss several studies that
have shown that exposure to RF radiation at cell phone frequencies
facilitated cognitive function
in human volunteers. See also "What's New" for February,
May, and September 2000.
has been reported showing similar findings. Edelstyn and Oldershaw
found improved performance in three of six psychological tests in
38 young male volunteers exposed to 900 MHz EMF. The results were
seen after 15 minutes of exposure. For more details, see the above
