- Hamamatsu professor invents speedy radiation detector
A researcher in Hamamatsu has created a postcard-sized device that can continuously take readings of radiation (gamma ray) levels caused by elements such as cesium at a rate of 40 measurements per second, even while the device is moving.
By combining the reading with locational data it can display a map with precise information on contamination.
"I hope it will help in evacuating residents and contribute to the recovery from the Great East Japan Earthquake," says Yoshihiro Takiguchi, 53, the device's inventor.
