✔ 最佳答案
Boradband routers emit electromagnetic waves (EM waves) of frequency 2.45 GHz. Those used in homes and in offices generally are of power of hundres mW (milli-watts).
A report by the Hong Kong Office of Telecommunication Authority (電訊管理局) published last December shows that the EM wave intensity around Wi-Fi Access Points throughout Hong Kong are only a few percent of the limit recommended by the International Commission on Non-Ionizing Radiation Protection (國際非電離輻射防護委員會). Wi-Fi routers are of much higher power than routers in domestic and office uses.
As said by the World Health Orgainzation(世界衛生組織), present scientific knowledge still could not establish a firm conclusion that exposure to radiofrequency EM waves (射頻電磁波) would cause adverse health effects.
