The Japanese Education, Science and Technology Ministry have issued a recall notice for 5,500 cell phone straps that contain the radioactive substance tritium.
The straps, not surprisingly marketed as “glow in the dark cell phone straps” had been on sale since the beginning of the year, although not with widespread distribution. The Hiroshima couple making the straps was arrested primarily for selling the straps without a license, although we’re not sure if they were pinged for the radioactivity later.
The amount of Tritium in each strap was generally safe for humans, although came in at 26 times the allowable level under Japanese radiation sickness prevention law. As the law requires a license for people handling radioactive material, those who purchased the straps may also be charged with violating the law.
