Japan: Ra-226 Found at Tokyo Residence


On 31 October 2011, a woman residing in Higashiyama, Tokyo's Meguro Ward alerted the authorities that radiation was detected on a wooden box in a storeroom. Inside the box, which had been kept in the room for about 50 years, authorities discovered a small (2 cm in length and 3 mm in diameter) metal container with Ra-226. According to the Ministry of Education, Culture, Sports, Science and Technology, the material must have been produced for medical purposes. The container with the material was removed.
