Robert -

Regarding your question about dermal absorption of actinides, you might take a
look in ICRP Publication 48, "The Metabolism of Plutonium and Related
Elements."

Naturally, this is only my humble personal opinion, and does not necessarily
reflect those of my august employer or it's august regulatory agency.

hence the following question to the Radsafe community.

1) Has anyone come across or know of dermal absorption coefficients for
actinides or heavy metals or calculated radiological doses for the dermal
exposure pathway.

The only reference that I have found to date that comes close is from
EPA/600/8-91/011B, and this only deals with tritium. Logically, a transfer
coefficient for heavy metals should be extremely small, however we need a
citable reference/methodology. Use of EPA default absorption coefficient may
not be feasible.
