In general, you'll see creepier behavior with higher E and/or shorter
t1/2.  Let me think on't for a good reference.

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).

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.
