radioisotope inventory software?

[xp4y at vax5.cit.cornell.edu]

Does anyone know of a software package (either commercial or homebrew) that can
be used to keep track of radioisotope inventories, waste disposal, etc.,
including decay calculations?  Maybe some type of spreadsheet program.  I'll
post a summary of any E-mail responses I get if there's enough interest.

Thanks in advance.
