[ RadSafe ] Po-210 particle mobility

[KARAM, PHILIP]

There is an interesting line in a paper by Stannard and Casarett from a 1964 paper:

"Finally, the tendency of polonium-210 to "creep" from containers holding solutions or to become detached from the best-plated and protected substrates has contributed to many instances of unexpected area contamination."

There is no citation accompanying this statement - it seems to have been considered common knowledge at that time. The paper is:

Stannard JN and Casarett GW. Concluding Comments on Biological Effects of Alpha-Particle Emitters in Soft Tissue as Exemplified by Experiments with Polonium 210. Radiation Research Supplement 5, 398-434 (1964).

Subject: [ RadSafe ] Po-210 particle mobility

Does anyone have any references for the mobility of Po-210 particles?

I've read Otto Raabe's excellent work on Pu-238 mobility, and when I was looking into Pu-238 mobility many experienced "old guys" (who now might not seem so old...) told me that Po-201 was even more mobile, but I never saw anything in literature.

Thanks,
Brian Rees
