Homework Help: geo/science

Posted by bex on Thursday, April 19, 2007 at 9:53am.

could you please tell me if this is the correct formula for radiometric date

t=1/constant 1n (1+d/p)

many thanks
ps this is a fantastic website

I think that you are after

t=1/[ln(1+D/P)]
where:
t = age of the sample
D = number of atoms of the daughter isotope in the sample
P = number of atoms of the parent isotope in the sample
= decay constant of the parent isotope
ln = natural logarithm
