The British government is going to take another look at the effects wireless networks may have on our health:
The research will aim to establish average exposure to the low level radiation emitted by wi-fi access points and wireless links on computers.
The HPA said it expected the results of the research to be "reassuring".
In its statement outlining its intentions, Professor Pat Troop, chief executive of the agency, said there was "no scientific evidence to date" that wi-fi or wireless local networks could have an adverse effect on the health of the general population.
The signals used on wi-fi networks were very low power, said the HPA, and well within guidelines issued by the International Commission on Non-Ionizing Radiation (ICNIRP).
"Given this, there is no particular reason why schools and others should not continue to use wi-fi or other wireless networks," said Prof Troop.
However, she added, little work had so far been done on the exposure of the average person to wi-fi networks. The research will aim to establish a baseline for this exposure.
