One trillion Bq released by nuclear debris removal

The operator of the damaged Fukushima Daiichi nuclear plant says more than one trillion becquerels of radioactive substances were released as a result of debris removal work at one of the plant's reactors.
Radioactive cesium was detected at levels exceeding the government limit in rice harvested last year in Minami Soma, some 20 kilometers from Fukushima Daiichi.
There are fears that some rice paddies in the city have been tainted by airborne radioactive material released when debris was removed from the plant's No.3 reactor in August last year.
On Wednesday, Tokyo Electric Power Company presented the Nuclear Regulation Authority with an estimate that the removal work discharged 280 billion becquerels per hour of radioactive substances, or a total of 1.1 trillion becquerels.
The plant is believed to be still releasing an average of 10 million becquerels per hour of radioactive material.
Municipalities around the plant are seeking solid measures to prevent the spread of radioactive substances, as workers prepare to dismantle the covering of the No.1 reactor building to remove debris there.
