Description
Contaminated soil and incineration ash collected during offsite decontamination work following the accident at the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co., Inc. is being stored in flexible containers. These containers are managed taking their activity level into account in accordance with the Decontamination Guidelines issued by the Ministry of the Environment. Toshiba has developed the 'Becquerel Screening' device that can automatically measure the activity level of the contents of each flexible container simply by placing the container on a palette, without the need to take samples for analysis from the container. The Becquerel Screening device is expected to contribute not only to improved operational efficiency but also to reduced exposure of operators to radiation, because it eliminates the need for direct contact with contaminated soil and ash.
