How hot is your house?
Scosche’s RDTX is a radiation detector for your iPhone. Seriously, it turns your iPhone into a Geiger counter—you just attach the wand to your iPhone and the RDTX will tell you the radiation levels around you…
Once attached to your phone, the RDTX displays results in a digital scale or classic green/yellow/red analog needle on your iPhone. The radiation detector can even average out how much radiation you expose yourself to, find out the total dosage, ring an alarm if it gets too high and even update Twitter/Facebook/Google Maps (to map out radiation levels). It’s only out in Japan right now (and for good reason, obv) but could be extremely helpful anywhere nuclear disasters may happen.
