The majority of the world’s cellphone using population wouldn’t prefer living near a nuclear plant or a place that is prone to radiation exposure. But just in case you do happen to live in such a place, having a smartphone that can detect radiation would certainly be handy. The Sharp Pantone 5 (107SH) by the Japan-based cellphone carrier Softbank is one such option that combines the functionality of a regular smartphone with the additional luxury of doubling up as a radiation detector. The phone came into being as a response to the panic caused by the possibility of radiation leakage from the Daiichi Nuclear Power Plant in Fukushima last year after the horrendous earthquake and tsunami.
