The government has ordered a wide-ranging investigation into wireless computer networks amid concerns over the potential health risks they pose for millions of schoolchildren and office workers.The Health Protection Agency (HPA) will spend two years conducting lab tests and monitoring exposure levels to the wireless signals in classrooms, homes and offices, before compiling a health risk report on the technology.Fears over the potential risks of wireless networks have led some school governors to order their withdrawal from classrooms.
