Concerning uranyl nitrate, incoming papers will emphazise the fact that
transferability is greatly a function of hydratation of the product, hence
its age (suprisingly, high humidity implies slower transfer). Experimental
results (in vitro) will soon be published.

Having recently posted a query concerning Thorium, I am very interested by
point 2 and 3.

Rem : members of the group supplied very useful material following my mail
about Thorium. In due time i will forword individual thanks and a summary
of our findings.

Best regards,
