It takes a certain amount of time for half the atoms in a sample to decay.

Radioactive dating is helpful for figuring out the age of ancient things.

Carbon-14 (C-14), a radioactive isotope of carbon, is produced in the upper atmosphere by cosmic radiation.

The first is that atoms have always decayed at the same rate.

And this isn’t really an assumption as the decay rates have been tested in the laboratory for a hundred years or so, we have an example of a natural nuclear reactor where we can measure the various products and determine the decay rates (and the fine structure constant), and we can observe the past by looking deep into the past of the universe. The sigh isn’t for the effort of writing, it’s for the effort of finding all the references.

This stuff is important to know when using radioactive isotopes as medical tracers, which are taken into the body to allow doctors to trace a pathway or find a blockage, or in cancer treatments.

They need to be active long enough to treat the condition, but they should also have a short enough half-life so that they don’t injure healthy cells and organs.

The other is that the decay products of various atoms are always the same. Just looking at this list, I can see that none of these are actually assumptions used by radioactive dating methods and/or they are known issues and compensated for. Something that this particular website has none of. Basically, just like all creationists, they are making stuff up and then hoping you won’t check them on it. 1) atmosphere has always had the same amount of C-14 This is obviously in reference to carbon-14 dating of formerly living tissue.

This is also actually kind of trivial and easily determined in the lab. Let’s see what the Missing Universe Museum thinks are the assumptions of radioactive dating methods. I guess we have to start at the top and work our way down… During an organisms life, it takes in CO have the common 6 protons and 6 neutrons. However, due to some interesting nuclear chemistry (which I’ll go into if requested), there’s another version of carbon (called an isotope) that has 6 protons and 8 neutrons. Note that if the number of protons change, then the atom is no longer carbon. Amazingly (and unlike what is claimed by the creationists), scientists have known about a variety of methods that create carbon-14 and how those methods have varied over time. Well, we take a carbon sample from a material of a known age and date that. Basically, the calibration curves are off by no more than 16 years over the historical range (6,000 years or so) and no more than 163 years over the last 20,000 years.

Because of the inconsistencies and uncertainties of C14 dating, most archaeologists prefer historical dates over C14 dates.
