Radio signals for the next generation of mobile phone services can cause headaches and nausea, according to a study conducted by three Dutch ministries.
The study, the first of its kind, compared the impact of radiation from base stations used for the current mobile telephone network with that of base stations 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 (miles), transmits signals to mobile phones with an electromagnetic field.
"If the test group was exposed to third generation base station signals there was a significant impact ... They felt tingling sensations, got headaches and felt nauseous," a spokeswoman for the Dutch Economics Ministry said.
There was no negative impact from signals for current mobile networks.
However, cognitive functions such as memory and response times were boosted by both 3G signals and the current signals, the study found. It said people became more alert when they were exposed to both.
Handsets emit stronger radiation when they are used, while base stations transmit more constant levels of radio signals, exposing everyone within range.
