carbon dating doesn work

About me:
The carbon clock is getting reset. Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct. Carbon dating is used to work out the age of organic material — in effect, any living thing. The technique hinges on carbon, a radioactive carbon dating doesn work of the element that, unlike other more stable forms of carbon, decays away at a steady rate. Organisms capture a certain amount of carbon from the atmosphere when they are alive. By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon decay can be worked out, thereby giving an age for the specimen in question.

Perhaps no concept in science is as misunderstood as "carbon dating. But, carbon dating can't be used to date either rocks or fossils. It is only useful for carbon dating doesn work things which still contain carbon, like flesh or bone or wood. Rocks and fossils, consisting only of inorganic minerals, cannot be dated by this scheme. Carbon normally occurs as Carbon, but radioactive Carbon may sometimes be formed in the outer atmosphere as Nitrogen undergoes cosmic ray bombardment. The resulting C is unstable and decays back to N with a measured half-life of approximately 5, years.

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C, and the old C starts to decay back into N by emitting beta particles. Carbon dating doesn work older an organism's remains are, the less beta radiation it emits because its C is steadily dwindling at a predictable rate. So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is.
