It is assumed that the ratio has been constant for a very long time before the industrial revolution.Is this assumption correct (for on it hangs the whole validity of the system)?(Ham et al., page 72.) As with Assertion 1, Assertion 2 fails to account for the tree-ring calibration which is a routine part of modern radiocarbon dating.

(Ham et al., page 68.) C ratio in the past, or that this is "the technique's Achilles' heel" is incorrect.

The whole validity of radiocarbon dating for the past 10,000 years---the time span of interest to biblical chronology---hangs only on the tree-ring chronologies which are used to calibrate it. .) This process does not involve any assumption about historic radiocarbon to stable carbon ratios because the radiocarbon concentration in the tree-ring samples would be affected in exactly the same way as the radiocarbon concentration in the specimen to be dated. To quote again from The Answers Book: Some recent, though controversial, research has raised the interesting suggestion that c (the speed of light) has decreased in historical times. If it is correct, then radioactive decay rates would automatically be affected, and would show artifically high ages.

Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.

It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.

This idea is advanced, for example, in The Young Earth: C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.

How do we know what the ratio was before then, though--say, thousands of years ago?

Such raw ages can be calibrated to give calendar dates.
