Cesium-137 contamination: Fukushima amounts to four Chernobyls
May 24, 2012
TEPCO’s new estimates suggest that its Fukushima reactor has released more than quadruple the amount of radioactive cesium-137 leaked during the Chernobyl disaster. But the method used to measure the damage may undervalue the hazard even further.
[...] it still seems to be just an effort to downplay the real scale of the event.
The report goes on to compare Fukushima with the Chernobyl accident of 1986, where it says 5,200,000 TBq of “radioactive substances” were leaked into the atmosphere.
The problem is that TEPCO only counts the amount of iodine-131 and cesium-137 leaked from the Fukushima reactor, and compares them to the whole range of isotopes that were discharged at Chernobyl.
And if compared properly, the numbers tell a different story.
Regarding the emission of cesium-137, Fukushima is far ahead its rival. Post-Fukushima estimations suggest that Chernobyl put out a total of 85,000 TBq of caesium-137 over the course of the disaster. The Fukushima reactor, however, has so far released 360,000 TBq of cesium-137, according to TEPCO.
