原來福島果次都係大量排放radioactive noble gas:
Xenon-133 and caesium-137 releases into the atmosphere from the
Fukushima Dai-ichi nuclear power plant:
Regarding 133Xe, we find a total release of 15.3 (uncertainty range 12.2–18.3) EBq, which is more than twice as
high as the total release from Chernobyl and likely the largest
radioactive noble gas release in history
