As I pointed out in my contribution, which I forward to your private
address once again, the tritium concentration depends on a a large number
of factors. This has nothing to do with detection statistics!

I do not know, what graph you refer to. I do not know, whether it is ground
water, precipitation, surface water, water from glaciers, from air moisture
and especially from which year etc. etc. I have too much of high esteem for
Merill Eisenbud, whom I had the pleasure to meet personally, to believe
that he had not taken into consideration the factors I just referred to.
