When I'm using my laptop at home I usually rest it on my lap (obviously). Can this cause cancer in my testicles or stomach or anything? Is it killing my sperm count? Is it a stupid thing to do? — W. Riley, Nashville, TN
Laptops and other computers have to meet certain FCC criteria to make it to market. One of those criteria is that the device not radiate energy in the radio frequency spectrum. This was great until the invention of Wi-Fi — now your computer is designed to emit radiation. So what is this doing to us?
The good news is that there is no consistent data showing that exposure to radio waves from laptops is dangerous to your health. A study by a European governmental agency concluded that "there is no consistent evidence to date that exposure to RF signals from Wi-Fi and WLANs adversely affect the health of the general population. The frequencies used are broadly the same as those from other RF applications such as FM radio, TV and mobile phones."
Until further studies are done, it seems that computing is relatively safe. Unless you're cruising the "Hot Wives of Giant Rednecks" sites, in which case, good luck.
