Is a wireless network safe?
The verdict is still out, but there is little evidence for the idea that wireless networks have a negative impact human health.
Popular concern over microwave radiation from wireless computer hubs (wifi routers) dates back several years. The Times of London and the NY Times have both reported on the issue. Many public places (fast food restaurants, coffee shops, waiting rooms) now have free wifi hot zones. The increased exposure to wifi hot zones has fueled public concern.
The World Health Organization says the signals emitted by routers are safe, though they pose a health risk in the sorts of high concentrations found in some industrial environments. A few studies of brain cancer patients have had patterns of long term cell phone use among the patients. But cell phones emitted a higher amount of radio waves than wifi routers from a closer proximity to the body.

Yes, but the network and the computers that are on the network have to be configured correctly for it to be safe. On the wireless station, WEP (Wireless Encryption Protocol) can be used to encrypt the signal that is being sent and received. On the network computers, passwords and permissions should be setup.
