Comment So .. how do they calibrate it? (Score 1) 133
IIRC, decent dosimeters require re-calibration at least yearly if not more often. (Sounds like they don't respond well to sudden shock and this increases accuracy drift.)
I wonder how SoftBank is going to handle this. I don't think people are going to appreciate a test sample being delivered to their home, and I think employees wouldn't appreciate it in stores/kiosks. I know 7Elevens sell everything in Japan, but not sure this is going to fit in well on the kombini scene.
Similarly, I don't think having the phones sent to the factory will work. It's a tad inconvenient.
