Tom, 

I think you need to use the Bateman equation for determining the progression

of radioactive decay.  Try http://www.nuclides.net/DecayEngine.htm  Then

calculate it for whatever times you want.

Subject: chains in equillibrium



Radsafers,

Can anyone provide a reference that provides information on the relative 

intensity of the gamma rays emitted by a chain of isotopes that is in 

equilibrium?
