Each of the 150-kilogram containers holds a single capsule with about one cubic centimetre of Cesium-137. If taken out of its containers, the capsule can radiate up to 400 roentgens per hour, says Pyotr Lazarev at the police headquarters in Volgograd in an interview with The Moscow Times.
Radioactive cesium believed to have been released during the crisis at the Fukushima No. 1 nuclear power plant in Japan following last years major earthquake has been found in plankton about 375 miles east of the facility, according to a Japan-U.S. joint research team.
Internal radiation exposure is caused mainly by the ingestion of radioactive substances in food. To prevent the overconsumption of food contaminated with radioactive substances, the reference value for radioactive cesium has been established as 100 Becquerelskilogram. This reference value was created to ensure food safety for all age groups.
