Do you use cordless/wireless/DEC phone in your home? Wireless network use the same frequency band as dec phone. I think that transmission energy must be similar.
If you are worry, only switch it on when you need it and do not put any wireless device close to your head.
The problem is that it is almost impossible to prove no health risk, just same as mobile phones. But mobile phones use higher frequency and transmission energy is much big because phones need to communicate with base station from a long distance and also people put phone close to their head.
I'm still interested in people's thoughts on this. I'm about to buy a laptop and wireless networking at home would be very useful. However, I'm still not convinced one way or the other about health risks. Do you use Wi-Fi? Are you worried that it may affect your health? Please let me know your thoughts!!
No problem, the output power of WiFi is 100mW or 0.1 Watts, compaired to the mobile phone with power levels of between 0.5 - 4 Watts which you put up to your ear 'ole, you are unlikely to do that with WiFi.
By the way, the inverse square law applies to radio frequencies, since doubling the distance gives a four fold reduction in signal power, so the field strength from a WiFi antenna will be extremely low.
I still cant get mine to work - let alone worry about health risks ! Its nice to see somebody remembers physics & maths from school. I personnaly dont think it can do much harm unless you stand with your earhole on the antennea for 20 days !
