C14 is only found in organic remains or in the atmosphere.

How about NO.

C14 has been measured in volcanic gases.

ABSTRACT. Radioactive nuclides such as radiocarbon can be good tracers for investigating the circulation of underground carbon and water. Volcanic gas can be sampled reliably for 14C analysis and prepared for analysis by accelerator mass spectrometry (AMS). In this paper, we establish a method for the measurement of 14C in volcanic gas, and measure the amounts of 14C in various volcanic gases. Samples of fumarolic gas from some Japanese volcanoes were found to contain 0.5 to 4.2 pMC, while those from White Island in New Zealand contained 2.6 pMC. Dissolved gas from Lake Nyos, Cameroon, contained 0.4 to 4.8 pMC. The data indicate a mixing process between surface carbon and deep carbon.

1) It's first immediate application is : it is obviously that we have a new known case of the reservoir effect. We already knew of marine reservoir effect, carbonate reservoir effect, now there is also volcanic reservoir effect.
2) Next we have the question whence the pmC content comes.
a) it could be produced by radioactive processes in the volcano, so, anything that has an unexpectedly high pmC content could have the extra from neutron contamination by the volcano, or by admixture contamination from the air;
b) or it could be that all of this is variation reflects the variation of the original pmC content at the time of the Flood. I'll check the implication for that in a moment.

My analysis:

4980 years since the Flood
0.5^(498/573) = 0.5474845100674124

0.4 pmC = x1 * 0.5474845100674124
4.8 pmC = x2 * 0.5474845100674124

x1 = 0.4/0.5474845100674124 = 0.7306142779286075839 pmC
x2 = 4.8/0.5474845100674124 = 8.7673713351432910067 pmC

Carbon date range for the Flood:

x1 => 40 700 extra years + 4980 = 45680 BP
x2 => 20 100 extra years + 4980 = 25080 BP

So, if we take this as coming from the Flood, we get:
a) pmC varied between at least 0.73 pmC and 8.767 pmC
b) carbon dates from exactly the Flood would vary between at least 25 080 BP and 45 680 BP
c) which is consistent with my attempt at unifying it at 39 000 BP, which would instead then be one of the possible dates (that of Campi Flegrei)
d) which is also pretty consistent with the CMI ballpark 20 000 BP to 50 000 BP.

Hans-Georg Lundahl I don’t quite follow you but that’s ok.

Resumé:

IF the Flood was 5000 years ago, IF the levels mentioned are levels at the time of the Flood and then decaying, THEN the levels at the time of the Flood are compatible with:

• both the CMI ballpark of Flood 20 000 to 50 000 years ago
• and my own Flood date at 39 000 years ago, except it was less uniquely true for all Flood fossils.
