TEPCO has retracted the chlorine-38 measurements they published a couple of weeks ago.
There was much chortling over those measurements, because about the only way you could get chlorine-38 would be if there were "re-criticalities," if the fuel in the reactor cores or possibly the fuel pools were becoming critical again. I pointed out the improbability of such things happening.
I hope that now those who were looking for the worst will retract their overblown interpretations of China-Syndrome-type meltdowns, fires in the fuel pools, and those unexplainable "localized criticalities."
This is why I haven't been rushing to interpret every single number that comes out of Japan, particularly when it's a stand-alone number like the chlorine-38. The demand that TEPCO release all its information (first comment on Jeffrey Lewis's post) is out of line. If people weren't rushing to be the firstest with the worstest, they wouldn't have to feel dumb when the conclusions they've jumped to turn out to be incorrect. And radiation-measuring instruments are prone to error.
Plus, you know, the people they're asking to provide all that had, like, an earthquake and a tsunami, as well as some reactors to take care of?
