Fish containing 180 times the permissible level of caesium found in Fukushima

A fish caught near the ruined nuclear power plant (核電廠) in Fukushima (福島) was found to contain an excessive amount of the radioactive element caesium (銫), exceeding the permissible (許可的) level set by the Japanese government by 180 times. Caesium is one of the by-products (副產品) of nuclear power plants.
