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.
Radiocarbon dates can be obtained from many types of organic material including charcoal, shell, wood, bone and hair.
Six of these models are based on a creation as described in Genesis and a short age of life on earth.
The solution containing the collagen is separated by G5 glass filter and evaporated.
The insoluble remains contain the inorganic parts and the humic acids as insoluble salts.
When the organism dies, the carbon 14 (C14) atoms disintegrate at a known rate, with a half-life of 5,700 years.
It is possible then to calculate the date of an organic object by measuring the amount of C14 left in the sample.
