What is the Source of This "Contamination"?
If we assume that the "contamination" is somehow a product of the counting process, we could than narrow the possibilities down to two :
|Comparison of C-14 Age Samples|
without a sample
|60,000 - 73,000|
| >90,000 or no counts
in a 30 minute run
|63,500 +- 2,000||Geological Graphite||69,030|
|56,000 +- 1,500|
prepared slightly less carefully
|58,590 - 65,840|
|54,000 - 64,000|| C-12 from the Faraday|
cup of the Accelerator
"Infinite" Age Sample
Anthracite, bone, calcite,
Graphite, limestone, shell, wood
|40,000 - 52,000|| "Infinite" Age Sample|
Anthracite coal, marble
|"up to 52,000"|

Looking at the data to the left, we see the results of two research groups trying to grapple with the source of the contamination. Both groups measure high background counts. Yet, they consistently measure "infinite" age fossil carbon samples only in the 40,000 - 52,000 age range. In addition other sources of carbon do yield ages older than the "infinite" age fossil carbon samples.
Because of the fact that other types of Carbon as well as the background, give counts indicating the presence of much lower levels of C-14 (giving longer ages); We can safely make the point that neither the possibility of sample contamination nor machine background is adequate to explain the source of the C-14 in the "infinite" age fossil carbon samples.
Since the counting process does not seem to be the source of the "contamination", lets assume that the "contamination" is somehow a characteristic of the sample itself. There are three possibilities for the presence of the C-14 in the sample.
To consider a source contamination of all states of fossil carbon (coal, oil and natural gas) we would have to have a worldwide exchange involving at least 50% of the entire Biosphere with all types of fossil carbon to give the level of C-14 that we see in samples. In addition that worldwide exchange would have to be so pervasive that similar levels of C-14 would be present in all type of fossil carbon regardless of the state.
This level of contamination is hard enough to believe with oil and gas, but would be extremely incredible with coal!
In situ formation of C-14 has been ruled out by others in the field. "Subsurface production of radiocarbon is negligible (Zito et al. 1980) (Florkowski et al. 1988)
The only other possibility is the presence of residual activity. Fossil carbon would then have to be quite young. If this result holds up over time, it would mathematically eliminate the whole evolutionary time scale. There would be no possible way for the geologic column to be 60 - 600 million years old.
It must be remembered that this is still not a proof for short age. It is still possible for one of the other sources of contamination that I have eliminated, to still be the cause of having C-14 in "infinite" age fossil carbon. However, at the present time, I believe that the evidence strongly supports the Creation model.
You can be sure that this will be the subject of intense research by various Creation research groups in the future. If and when their research gets reported I will post the specific Journal so you can look up the paper yourself. I am sure that some of them will also be on the web. I will have links to those sites. Come back for any new developments.
