ICR creationists claim that this discredits C-14 dating.
Finally, elsewhere Clement states that the teaching of the Apostles was completed at the time of Nero.
Domitian was not a nice fellow, to be sure, but to call him a "tyrant" would be to waste the word needlessly when there is someone else who deserved it better.
But other species produce scarcely any extra rings.
However, in either case, the background beta radiation has to be compensated for, and, in the older objects, the amount of C-14 they have left is less than the margin of error in measuring background radiation.
Question: Creationists such as Cook (1966) claim that cosmic radiation is now forming C-14 in the atmosphere about one and one-third times faster than it is decaying.
As Hurley points out: Without rather special developmental work, it is not generally practicable to measure ages in excess of about twenty thousand years, because the radioactivity of the carbon becomes so slight that it is difficult to get an accurate measurement above background radiation.
This means that the tree-ring dates would be slightly too young, not too old.
Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.
For that was seen no very long time since, but almost in our day, towards the end of Domitian's reign.(Against Heresies :3) This quote, preserved for us by Eusebius, offers a puzzle: Who, or what, was "seen" almost in Irenaeus' day?
