Molten Uranium

[mcnaught@lanl.gov (Mike McNaughton)]

Does anyone know of actual measurements of the dose rate at the surface of
molten uranium. It is said that the Th and Pa daughters concentrate on the
surface, thus increasing the dose rate. However, the thermal energy of an
atom is so much greater than the gravitational potential energy that the
thermal motion (Brownian motion) will counteract this, to some extent. Are
there any actual measurements of how large this effect is?

Thanks, mike
