I am going for a holiday in Japan but is worried about radiation exposure.
It seem, according to the US media, the Japanese authority there is grossly under reporting the Fukushima nuclear disaster.
So I am thinking of buying one of these device, to take along.
Has anyone bought and use one of these iPhone add on that turn it into a Geiger counter?

Would like to hear from any user out there, as to it's effectiveness.
