internet dating benefits - Radiocarbon dating diamonds

Anyone have any ideas about this apparent anomaly with C14 in coal? supposedly has an article on this very subject (per Google), but I haven't been able to get to talkorigins for some time. The small apparent non-zero values are less than measurement error.

In other words, the readings are consistent with zero C14 content.

The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.

Ninety-nine percent of these also contain six neutrons.

The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.

As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).

This fact should always be remembered when using radiocarbon dates.For radiocarbon dating to be possible, the material must once have been part of a living organism.This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.In fact, the experiments cited by the creationists appear to be attempts to establish the measurement error of there equipment.Older carbon dating techniques directly detected decays of C14 atoms. The most common contaminant is nitrogen, 0.1% in gem-quality diamonds.Common materials for radiocarbon dating are: The radiocarbon formed in the upper atmosphere is mostly in the form of carbon dioxide. Because the carbon present in a plant comes from the atmosphere in this way, the radio of radiocarbon to stable carbon in the plant is virtually the same as that in the atmosphere.
