The large internal Plutonium contamination incident widely reported earlier
this week, may actually be entirely incorrect. The National Institute of
Radiological Sciences (NIRS) in Chiba has examined all of the men. NIRS
says they can find no internal contamination of the lungs in any of them!
That's right! Nothing detectible!
The alleged internal radioactivity activity(s) reported earlier this week
disappeared after the NIRS administered "proper decontamination". The JAEA
said it believes the initial readings resulted from transuranic
contamination detected on the men's skin prior to undergoing
decontamination.
http://www.asahi.com/ajw/articles/AJ201706100022.html
Numerous possibilities immediately come to mind. First, JAEA might possibly
have the most incompetent HP staff imaginable. Second, Japan's decidedly
antinuclear Press may well have made another mountain out of a mole-hill,
a-la the "soaring radiation levels" in F. Daiichi unit #2 broadcast earlier
this year. It's been more than six years since the nuke accident, and they
still have no clue. Third, even if the dude actually had 22,000 Bq of
Plutonium in his lungs, it appears that the reported 1.2 Sievert exposure
in the first year and 12 Sieverts lifetime are gross exaggerations. Fourth,
Nuclear Regulation Authority commissioners criticizing the workers for
"complacency", will have considerable egg on their faces. I could go
on-and-on!
What a ridiculous mess!

> I am also interested in understanding how the CED should be interpreted in

> inhalation, i.e. shortly after the time of the inhalation. For each Bq of
> Pu-239 a given dose is given.
> If instead an estimate of the present activity is made 10 days after the
> event then the value at 10 days is used, taking into account the dose up to
> that time and the fact that the activity at the time of the intake was
> higher than now.
> Is this a correct interpretation?
