Next-Generation Mobile Signals Shown to Cause Nausea,
Headache

AMSTERDAM (Reuters) Sept 30 - Radio signals for the next generation
of mobile phone services can cause
headaches and nausea, according to a survey conducted by three
Dutch ministries on the impact of tomorrow's data
networks on health.

The study, the first of its kind, tested the impact of radiation
from base stations used for the current mobile telephone
network, against those for new third generation (3G) networks for
fast data transfer, which will enable services
such as video conferencing on a mobile device.

A base station, which usually covers a 'cell' area of several
square kilometers, transmits signals to mobile phones
with an electromagnetic field.

"If the test group was exposed to third generation base stations
there was a significant impact. They felt tingling
sensations, got headaches and felt nauseous," a spokeswoman for the
Economics Ministry said.

There was no negative impact from the signals for current mobile
networks.

However, cognitive functions such as memory and response times were
boosted by both 3G signals and the current
ones, the study found. People become more alert when they were
exposed to both.

The Dutch ministers responsible for Economic Affairs, Health and
Telecommunications said follow-up research was
needed to confirm the findings. They also said any longer-term
health effects and biological causes needed to be
looked at.

They will also discuss the study with the European Commission, the
spokeswoman said. The double-blind laboratory
tests exposed test subjects to levels of radiation average for
third generation networks when they become
commercial in coming years.

The GSM Association, an organization of mobile telecommunications
operators, was not immediately available to
comment.

The study was conducted by the Dutch technological research
institute TNO.
