Fukushima I Nuke Plant: Krypton-85 and Xenon-131m in Reactor 2 Containment Vessel Air Samples, EX-SKF, August 11, 2011:
Half life of xenon-131m is about 12 days [...]
[W]hat’s with krypton and xenon? I also read a tweet by one of the workers at the plant who said there is still radioactive iodine being released, even though TEPCO’s monitoring says iodine-131 is not detected at the plant any more.
See TEPCO’s August 10 handout here.
