No observations on my students' Normality? :-)

You're correct, of course.  I do believe that the radioactive decay of a
pound of U-238 over a month is a Poisson process, but on timescales
close to the half-life it is not.  Smaller samples or isotopes with
shorter half-lives would not be.  That's what I get for
underspecification. :-)
