– 10 million Bq of cesium-134/137 is still released every single hour from reactor1, 2 and 3 (Fukushima Diary,Dec 27, 2012):
According to mid/long term roadmap of Tepco released on 12/27/2012, 10 million Bq of cesium-134/137 is still released from reactor 1, 2 and 3 every single hour.
This is measured at the top part of each reactor building. The amount is computed from the dust density of Cs-134/137, other nuclides are excluded.
Since this April, the releasing amount has been stably around 10 million Bq / hour.
