Type radiation used carbon dating
If you were using a geiger-type counter (which can't determine the energy or type of radiation) to determine the sample's radioactivity, then absolutely any other ionizing radiation would trigger the detector and prevent an accurate age determination.I'm not sure, to be honest, but I assume typically a spectroscopic detector is used for C-14 dating.But the question is, when does an atom or nucleus decide to decay? So it could either be beta decay, which would release electrons from the neutrons and turn them into protons. And normally when we have any small amount of any element, we really have huge amounts of atoms of that element. That's 6.02 times 10 to the 23rd carbon-12 atoms. This is more than we can, than my head can really grasp around how large of a number this is. Let's say I have a bunch of, let's say these are all atoms. And let's say we're talking about the type of decay where an atom turns into another atom. Or maybe positron emission turning protons into neutrons. And we've talked about moles and, you know, one gram of carbon-12-- I'm sorry, 12 grams-- 12 grams of carbon-12 has one mole of carbon-12 in it.

What methods do they use and how do these methods work?
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
I understand that carbon dating is the measurement of the degradation of Carbon14. C-14 dating has been noticeably impacted by human-produced C-14, mostly from nuclear testing since the 1950s.
If, in the case of human remains, an individual received extra radiation due to atomic bombs, mercury poisoning, etc, could that skew the dating process? People who actually do C-14 dating use a calibration curve to adjust the naïve results given by their tests to better match the actual history of C-14 production on our planet.A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
