Homework Statement
Radioactive decay is:
N = N0e-λt
N can also be used to describe count rate after a time, (t) where N0 is intial count rate and λ is decay constant...
Half life, t1/2 od radioactive isotope is
t1/2 = 1n2
λ
The λ should be under the ln2 but it won't let me underneath
How do I calculate 1n??
For example if time (t) in minutes is 10 and Count rate in 1 minute (N) is 82 what is 1n
I don't understand at all? Any helps is grealty appreciated
Thanks
