A Japanese mobile phone operator has cashed in on residual fears from the Fukushima nuclear accident by designing a smartphone with a built-in radiation detector.
Softbank Corp claims the phones are more compact and user-friendly than conventional geiger counters, which have become a familiar sight in some parts of the country.
The company announced today that it would begin selling the phones this summer at an "affordable price".
Although there is an exclusion zone around the nuclear plant and all residents have been evacuated, there are still concerns about nuclear hotspots along Japan's eastern coast. Anti-nuclear activists have campaigned for radiation monitoring in schools.
Softbank president Masayoshi Son said: "The threat from the nuclear accident cannot be seen by the human eye and continues to be a concern for many people, especially for mothers with small children."
