Note that Samsung is only one Android vendor, and is outperforming iPhone. There are several other Android vendors with large sales as well: HTC, ZTE, LG, Motorola, etc.

15 microSieverts / hour corresponds to ~150 milliSieverts / year though, which according to the xkcd graph means "lowest one-year dose clearly linked to increased cancer risk" (100 milliSieverts / year) and is 100 times higher than the limit set by the EPA in the US.

So as long as the level is 15 microSieverts / hour, then nobody will be allowed to live there. As I said above, the level is 100 times higher than the allowed habitable limit.

America has just spent the last 5 years torturing people and invading a country against international law with American soldiers massacring its population with impunity. It's a terrible role model for democracy.
