It is based on the idea that a pre-Flood vapor canopy protected the earth's atmosphere from cosmic radiation and thereby caused a decrease in radiocarbon production. .) Something like a vapor canopy could affect the atmospheric radiocarbon concentration, but this fact is, once again, irrelevant to the validity of modern tree-ring calibrated radiocarbon dates.

Assertion 3 is a special case of Assertion 1, and, like it, is false.

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.

(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.
