Carbon dating chicken bone
Soil contains organic material, but because of contamination by humic acid of more recent origin, it is very difficult to get satisfactory radiocarbon dates. In fact there is much evidence to show this rate has not remained constant, and that it is decaying quicker and quicker. Thirty thousand years is about the limit. Of these, humins give the most reliable date as they are insoluble in alkali and less likely to contain contaminants from the sample's environment.
The isotope concentrations can be measured very accurately, but isotope concentrations are not dates. An international team of creationist scientists is actively pursuing a creationist understanding of radioisotope dating.
They should not change the facts to fit the theory. They too, give varied results.
That is how radiometric dating works. Look at the world from a devolutionary viewpoint and see how perfection has been lost and breakdown has proceeded in spurts and stasis periods.
It makes no sense at all if man appeared at the end of billions of years. The age they came back with was only a few thousand years old. Potassium-argon dating The potassium-argon method was used to date volcanic material in this next example. Again, this indicates a maximum age, not the actual age. Again, the stories are evaluated according to their own success in agreeing with the existing long ages belief system.
So they start with the assumption that dinosaurs lived millions of years ago, then manipulate the results until they agree with their conclusion. Decay rates have always been constant. The atheistic evolutionist W. Because he assumed that the earth was millions of years old, he believed it was already at equilibrium. These contaminants are considered natural because they came in contact with the bones due to natural occurrences.
In this case the sample is often usable. This would make things look much older than they really are when current rates of decay are applied to dating. It is simply that all observations must fit the prevailing paradigm. In Australia, some wood found the Tertiary basalt was clearly buried in the lava flow that formed the basalt, as can be seen from the charring.
Radiocarbon dating results on bones need not be subjected to an age offset but bone samples have time-width. If the techniques were absolutely objective and reliable, such information would not be necessary. But the ones above give you a general idea. The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere. We will deal with carbon dating first and then with the other dating methods.
