Another Update on Radioactive Black "Dirt" in Japan

I recently posted about the highly radioactive black soil/dirt/mold or whatever it is being found in Japan.

Paul Langley, who writes the incredibly informative and interesting Paul Langley's Nuclear History Blog, sent me a comment about the potential nature of this black radioactive stuff:

[Paul Writes] Majia, the US reported and described a black sticky substance that caused beta burns to US service personnel in the pacific in 1948. 

The beta burns and source - sticky black substance - are described in the report here:  

Page 4: (Hoffman: A very important feature here is the black grimy material which adhered to the gloves of the personnel when they lifted these filter units from the fork. This black, non-powdery substance was hard to remove. Apparently this material was on the inner lining of the filter units. This material was probably the source of the high activity noted on the gamma meter)

And Australian Aboriginal people described it. I wrote it up here: 

Still frame images of Lallie Lennon and her injuries taken from the 1981 film “Backs to the Blast”.... I believe the suffering of Kukkika was caused by beta radiation burns. The photographs accord with those taken of people who suffered similar injuries in the Pacific as a result of US nuclear weapons tests. The US has acknowledged this. Kukkika was not the only Australian to suffer in this manner. Many people have, and do so still.

If the link does not work try googling operation sandstone radiation injuries zebra event. 

It might not be the same stuff.  

But if it is, it is condensed metal made radioactive by neutron bombardment. Least from memory that is was the black sticky fraction in the bomb fallout was.  It was the result of the vaporisation of metal. Now,  it may be condensed metal from the containment, the pressure vessel,  or something completely different, such as condensed fuel rod, who knows. or it might be something completely different of course.   

Fractionalisation. different components of the machine condense out at different temperatures and at different timings and fallout in different places.  Fallout is not a uniform representation of what was at the source.  

It lands according to the nature of each component, each element involved. There is some mixing of course,  by at various distances from point of origin, the composition of deposits on the ground varies in proportions. (with bombs there was a heavy, black, oily sticky substance, and a lighter bluish fraction which smelt like gunpowder.)  The US service personnel called the black stuff black goo. 

So there is a technical name. 

Best regards
