Regarding the last question that you asked about the iPad, if they have the iPad in airplane mode, then there's no problem. They're not being irradiated. However, there is now a device that you can connect to your iPad and hook it up through ethernet. As long as you have ethernet in your home, you can actually use the iPad. There's information regarding that on the web. We did it with my grandson and he's now as happy as a dumpling because we allow him to use his iPad, but it's not wireless. We have it in the wired way.
