Gas proportional counting in carbon dating

This technique works for objects that are up to 50,000 years old.This method of dating was introduced to the world by Willard Libby in 1949, and for this outstanding work, he was awarded the Nobel Prize in Chemistry in 1960.When cosmic rays collide with the atoms, it creates an energetic neutron, which, upon hitting a nitrogen atom (7 neutrons and 7 protons), creates a carbon-14 atom (6 protons and 8 neutrons) and a hydrogen atom (1 neutron, 0 proton).Carbon-14 is radioactive, and has a half life of about 5700 years.This includes aquatic animals which consumes some carbon from dissolved carbonated rocks.

When a living organism dies, its carbon intake ceases.For example, logs of woods cut from different trees were burnt in a fireplace.The sample of the end result would be contaminated.My observations show that proportional and drift chambers, together with multichannel electronics operating on-line with a computer, open new possibilities in ultra-low-level gas counting.To send this article to your Kindle, first ensure [email protected] added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

By comparing age of a sample deduced by using carbon-14 dating to results from other dating techniques, discrepancies have been noticed.
