Believe it or not, a case for iPad 1/2/3 was recently launched in the USA that promises to protect users from the "radiation" emitted by GSM/Wi-Fi chips. The case blocks Wi-Fi/GSM signal emission and of course also prevents it from reaching it, so as soon as you install it on the tablet you will not be able to access the Internet in any form, but you will be able to use the tablet for any other functions. I don't know how many people would be willing to buy such a product, though price $ 10 it must have attracted the interest of some, otherwise the case would not have reached the market.
