Is there any scientific paper on how radiometric dating is done? Like something written by someone who performs radiometric dating? Please someone end this madness.
There's also this one.

Don't know if that's possible...

This post is in response to the following

ORIGINAL: alex123
Various techniques can be used to apply absolute dates to some sediments. Older sediments often contain intrusions of igneous material that can be dated using a variety of techniques (‘daughter’ halides, isotope comparisons, isochrons) which show high degrees of convergence (Greenland pre-Cambrian). Younger sediments can be dated using C14, isotope comparisons, ice-core data and varve data, all of which again show remarkable convergence (Lake Vostok).
Natural Selection
In particular, read post 20.

I hope I'm not out-of-step for getting back on topic to the thread originator; radioactive decay constant.
I've always had a hard time relating to the "constant" part of radioactive decay, seeing as we have so many examples of non-constant decay: nuclear reactors and atomic bombs. I believe Iran is working on some accelerated decay of uranium right now.
So how does "constant" decay work? Does an isotope decay at a constant rate, just so long as there is not so much of it as to cause a chain reaction? Of course, I suppose we'd also have to restrict ANY OTHER fissable material from chain reacting too, that might be near enough that our isotope-under-test would "feel" the neutron flux of it? And nearby fusion reactions are right out. What about ultra-high energy photons, so called "cosmic rays"?
Then to be useful for dating, nothing like this can have happened for billions of years....
