While tech enthusiasts in the US and Europe are still getting used to seeing waterproof or dustproof smartphones, these features have been standard for a long time in Japan. However, aside from protection to water and dust, another “exotic” function is now being introduced in the “Land of the Rising Sun”.

The new Sharp Pantone 5 107SH smartphone has been unveiled by SoftBank and is set to be the world’s first ever handheld to come with an integrated radiation detector. That’s right, this little guy should give you an accurate measurement of radiation in your area upon its release and all you'll have to do is push on a dedicated physical button on the front of the device and wait for a few seconds.

Although that may sound like a very quirky feature to have on a smartphone for people in the US, you should know that Japanese have become alert to radiation levels ever since the “Fukushima Daiichi nuclear disaster” of 2011.

Sporting a 3.7-inch screen with 854 x 480 pixels resolution, the 107SH will be powered by a 1.4 GHz single-core processor and will feature a 4-megapixel rear-facing camera, Bluetooth 3.0, WiFi 802.11 b/g/n, the running of Android 4.0 Ice Cream Sandwich, as well as protection to water and dust.

As far as pricing goes, we have nothing official to report. The phone will be made available in mid-July, so we should find out soon enough how much money you’ll have to pay to get this unique piece of technology.
