As a result of the Fukushima Daiichi nuclear disaster following the March 11 earthquake and tsunami, radiation detectors have been a popular item for Japanese consumers. Recognizing the market for such devices, last month Scosche - a company known for its car audio and iPod/iPhone accessories - released its RDTX-Pro radiation detector and app for iPhone and iPod touch in Japan. With that model apparently flying off the shelves - it is temporarily out of stock on Scosche's website - the company has decided to expand the product line with the announcement of two new radiation detectors.
