Livermore has revised the transuranic data of Robison et alf(1982b),
and the present doses are about 50% higher. The entries in the fable
above are based only on chemical determinations (number of samples in
parentheses).
They are responsible for about 25% of the total
dbse which
Livermore now attributes to plutonium-239,-240 (.37 pCi/day) an
americium-241 (.13 pci/day}. The rest of the dose was estimated
