An investigation by BBC has revealed that wireless computer networks in schools can give off levels of signal radiation three times greater than a typical mobile phone mast. Government guidelines state that phone masts should not be sited near schools without consultation because children may be more vulnerable to radio frequency emissions than adults.

This investigation found that, at its peak, the signal radiation from Wi-Fi enabled laptops in a school in Norwich is more than three times that of a mobile mast. Following the publishing of this report, the Chairman of the Health Protection Agency called for a review of Wi-Fi technology.

Despite this, health authorities want to play safe and set guidelines for establishing low levels of exposure.

Tests have shown that children absorb more radiation than adults when using mobile phones, raising fears that the same could be happening with computers. The HPA has recommended that, as a precaution, children’s use of mobile phones should be limited. Many believe a similar approach may be needed for Wi-Fi technology, which is increasingly used in schools and public places.
