Relative Risks of Various Types of Radiation and Whether Internal or External

Moving kids back into areas of 20 mSv/year in Japan in insane at any level, but more insane when you consider that the radiation is assumed to stay all external.    The Rad Crap in and on the soil, and to be washed out of the air will all eventually go into food or water consumed by a  human.    It will almost all become internal  

So for our most likely suspects, Cesium, Strontium, Uranium, Plutonium, all long lived, all extremely damaging as internal with different weighting factors.

It is generally accepted that Alpha within the body is 20 times worse than a high penetration Gamma.    But where does the "20" come from,

it appears to be a number "that the nuclear industry can work with" per Paul Langley.   Now that 50% to 66% get cancer, you have to wonder how much understatement is going on.

But let's assume 20 is a good number for now anyway.     OK Cesium you can have Wr=20

How about Strontium?  The Bone seeker, some call it the bogeyman, the nukers want to keep Strontium (Sr) in the closet.    But Strontium is not just deadly all by itself, it decays to Yttrium 90 with a short half life of 2.5 days, at a wicked world class MMA punch of 2.2 Mev.   So think of your cells adjacent to the internal strontium as a human who takes a big hit from a strong street thug (Sr decay), and then 2.5 days later while you are still trying to recovery, Mohammed Ali comes up and super pounds you while in your already weakened state.   The worst thing for a cell is the double punch, this can cause a cancer or mutation.   Read more here.

So is Strontium accurately accounted for with the weighting of 20, or should it be 50 or 200.    Even in the current University offerings they use a cute “RBM” when talking about Strontium, would the average reader figure out this is for Red Bone Marrow, and that it leads to leukemia.

Plutonium, makes Strontium (the Bogeyman) look like a Leave it To Beaver episode.    We are mostly concerted with Pu239 of which

Fine particles of pure plutonium-239 oxide (formed when plutonium burns) are very intense sources of alpha particles.

          Geesaman and Tamplin have shown that such fine particles, referred to as "hot" particles because of their extremely high alpha particle emission in a localized region, may be 10 to 1000 times more effective in producing cancer than would be expected if the same number of rads were delivered in a more diffuse manner to an organ, such as the lung.

          It is this "hot" particle problem associated with plutonium-239 that makes the contemplated, future, widespread use of this radionuclide as a fuel in the nuclear-electricity-generation plants such an unmitigated nightmare for mankind.

So if we accepted the Weighting Factor Wr for Plutonium as 20 (and ignored it known nasty effect also as a very Heavy Metal) and considered the “repeated local attack” effect of Geesaman and Tamplin, then the true weighted Wr is in the range of 20*10, and 20*1000.     

On the most simple level, Plutonium should be weighted at Wr of 200 to 20000.

This study showed that Plutonium should be weighted at 112,000 compared to a basic Gamma blast.

The University of Michigan estimated the biological half life of Plutonium to be 50 years once in the bones, and 20 years in the liver.    Once in the blood, 45% will go to bones, and 45% will go to liver, and around .03% will go to testes or ovaries.

A lot of the links to radiation resources at the U of M website, seem to have been purged, per the Lawrence Livermore National Lab “In the National Interest” (see graphic below and check it out yourself)
