Homework Help: college geology dealing with carbon 14

Posted by student012 on Monday, October 20, 2008 at 10:27pm.

ok in my professors notes he calculates carbon 14 age in an example.

The problem goes like this:
Sample contains 110g carbon
sample produces 70 disintegrations per minute.
That is 0.7 disintegrations per minute.
T=(1/lambda)ln(N0/Nt)

Then he substitutes:
t=(1/1.209*10^-4/year)ln(1600/70)

I just want to know where did he get 1600 from?
