Softbank has just announced a new smartphone with a built-in radiation measurement function that is reported to be fairly accurate.
As I've stated ad-nauseum elsewhere, I think this is a very good trend. The democratization of basic gamma radiation measurement means it's harder for the government and companies like Tepco to fudge the figures, and it provides more data points for analysis.
