Specific Activity Computer Program for DOS/Windows???

[EUGENE JABLONOWSKI <JABLONOWSKI.EUGENE@EPAMAIL.EPA.GOV>]

Hello,

I have seen (a couple a years ago in DOS), and have been recently looking for a
computer program (DOS or Windows) that provides the specific activity for
radionuclides.

An alternative to a program would be a data file (ascii preferably) that would
list radionuclides and their half-life, atomic weight, etc.  I could use the
data table with a database program like Microsoft Access to generate the
specific activity info.  Better yet would be a data file with specific activity
info.  

I'm already aware of Rad-Decay (from the Grove Engineering) but that doesn't
provide specific activity data.

Any pointers to WWW, gopher, or FTP sites would be greatly appreciated.  If
someone has a program or data file they could e-mail me, I have the PKUNZIP and
UUDECODE utilities.

Thanks in Advance...
