Pu & Th Comparison?

[RadWizard@aol.com]

Let's all be careful when we compare Pu-239 to Th-232.  It strikes me as a
little disingenuous.

Sure, they are both alpha emitters, but look at the difference in specific
activity folks.  Convert the DACs (or DCFs) to a mass basis, then do your
comparison.  It is not clear to me that you could shovel enough Th-232 up
one's nose to get a sigificant dose.  Such is not the case with Pu.
