Describe how carbon 14 is used in radiocarbon dating

"This attitude is clearly reflected in a regrettably common practice: when a radiocarbon date agrees with the expectations of the excavator it appears in the main text of the site report; if it is slightly discrepant it is relegated to a footnote; if it seriously conflicts it is left out altogether." (Peter James, et al. It is for specimens which only date back a few thousand years.

Anything beyond that is problematic and highly doubtful. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.

2) This technique is best for dating items which died between on the order of 1000 to on the order of 1,000,000 years ago.

Carbon 14 dating is not great for dating things like a year old because if much less than 1 half-life has passed, barely any of the carbon 14 has decayed, and it is difficult to measure the difference in rates and know with certainty the time involved.

Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating. In order for carbon dating to be accurate, we must know what the ratio of carbon-12 to carbon-14 was in the environment in which our specimen lived during its lifetime.during the industrial revolution more carbon-12 was being produced offsetting the ratio a bit).Now living plants 'breathe' CO indiscriminately (they don't care about isotopes one way or the other), and so (while they are living) they have the same ratio of carbon 14 in them as the atmosphere.Animals, including humans, consume plants a lot (and animals that consume plants), and thus they also tend to have the same ratio of carbon 14 to carbon 12 atoms.
