Larry,
Cd-109 is used for x-ray fluorescence excitation in sealed source
form.  The only issue I ever encountered was impurities confounding
it's use in elemental quantitation.  But I have never been where it
is used in unsealed form.  I know cadmium is a problem in solders
where it may be a health problem when heated.  This is not likely
to be a problem.
 
Chlorine-36 is a hot beta emitter with a long half life.  It is used
here and I know of no particular problems except worry that if it
is spilled and causes contamination, there is no way to wait it our,
surfaces that can not be cleaned will likely have to be removed.
