Why are you hung up on electroplating? Perhaps you could plate from
acetonitrile or ionic liquids, but why? Likely the plated Sr will
oxidize in air and screw up your self-absorption coefficient anyway.
Or it may simply fall off the SS disk. (Still assuming you're doing
Sr-90.)

God made filter membranes for a reason.

EPA ect.. regulations for our lab state that I must use a sealed
electroplated source to calibrate my instrumentation. The are horrible
expensive to purchase. However I do have a lot of Sr-90 sitting around
in solutions. It would be very cost effiecent if I could create my
own. ( Also the man who signs my paycheck wants me to.)

If he signs your paycheck, he'll be willing to spend the time it takes
to solve the problem.

I'll give you the name of someone who knows everything about that
stuff.

A lot of electroplating and radionuclide wisdom is hopelessly locked
up in the gray literature from National Labs. The methods are hard to
find, and the people who know where to find them are retiring or
dying.

Interesting example of a regulation that conflicts with physical laws.
You aren't going to plate metallic strontium, and if you manage to
make a film of SrO or SrCO3, you can't count on it to be mechanically
stable.

Of course, there are people who simply spot solutions on the disc, but
you can't control self-absorption that way.
