Software to solve Bateman Equations

["Koperski, George" <George.Koperski@iluka.com>]

Radsafers

I am looking for a software program to enable calculations of an ingrowth
and decay of the radionuclides of Th-232 and  U-238 chains after  secular
equilibrium has been disrupted by removal of some of  the chain elements
(mainly various isotopes of U, Th and  Ra). Of primary interest is to
calculate the length of time required for the remaining radionuclides to
reach certain activity levels.  

I would most appreciate your  advice on where such program(s) may be
available from; including purchase, if necessary. 

Thank you
