Suggestions are offered for experimental projects that would resolve these uncertainties.

In this paper I will discuss eight categories of carbon-14 models and their experimental implications.

Differences between the models are specified, especially those that are subject to experimental testing.

Such features include (1) differences between ring years and radiocarbon years in trees that should be immediately postdiluvian by creationist theories, (2) the accuracy, or lack thereof, of the dendrochronological radiocarbon calibration curve in the historical era, and (3) the possible existence of carbon-14 in antediluvian fossil material.

CONSTRAINTS Any model of carbon-14 dating must satisfy certain constraints.

First, since carbon-14 dating is objective and reproducible, it cannot be ignored.

Nitrogen atoms high in the atmosphere can be converted to radiocarbon if they are struck by neutrons produced by cosmic ray bombardment.

The Beta-counting method detects the rate at which purified carbon decays. A rate of 7 decays/gram/minute would indicate an age of one half-life, or 5730 years old.

Once the radiocarbon atom is produced, it rapidly combines with oxygen (OC (7 neutrons) atoms.

Carbon atoms are incorporated into plant tissue (by photosynthesis) then into animal tissue (by ingestion) in nearly the same ratio as in the atmosphere. The Earth's magnetic field, its history, origin and planetary perspective.

Obviously this only works for things which once contained carbon—it can’t be used to date rocks and minerals, for example. We obviously need to know this to be able to work out at what point the ‘clock’ began to tick.

We’ve seen that it would have been the same as in the atmosphere at the time the specimen died. Do scientists assume that it was the same as it is now? It is well known that the industrial revolution, with its burning of huge masses of coal, etc.
