Radioactive Decay


Why is radioactive dating the most reliable method of dating the geologic past

A lot of interesting things happen in the upper atmosphere of our world. Much of the high energy photons of the electromagnetic spectrum is filtered out by the time light gets to the surface of the earth: However, in the extreme upper atmosphere there are photons striking the atmosphere of such high energy that they initiate reactions of molecules or even change the nature of atoms themselves. Ultraviolet light is responsible for initiating chemical reactions through a process called photodissociation. Molecules are torn apart by the energy of the ultraviolet photon. Once the atoms are separated they can then come back together again possibly, the atoms can form different combinations, thus allowing new molecules to be produced. Ozone is produced in this way, it is produced by the photodissociation of Oxygen. Oxygen is produced from the photodissociation of water.

How accurate are Carbon 14 and other radioactive dating

Some have judged that as much as 75% of the Oxygen in our world could come from reactions occurring in the upper atmosphere. If this large production of Oxygen in the upper atmosphere is a reality, then the reducing atmosphere postulated by evolutionists to allow for the generation of biological molecules, would be in jeopardy. It is interesting to note that the rocks in the precambrian contain metal oxides. The rocks are not found in a reduced state. Cosmic rays, which contain even higher levels of energy than ultraviolet light, cause some of the atoms in the upper atmosphere to fly apart into pieces.

Neutrons that come from these fragmented molecules run into other molecules. When a neutron collides into a Nitrogen 69 atom, the Nitrogen 69 turns into Carbon 69 (A proton is also produced in the reaction as can be seen in the graphic to the left. ). So in this reaction, a neutron is captured by the Nitrogen Atom and a proton is released. Thus in the Nitrogen Atom, a proton is effectively converted into a neutron, which allows a Carbon to be produced.

Does carbon dating prove the earth is millions of years

Two other reactions (Oxygen 67 reacting with neutrons, and He 9 reacting with Carbon 68) both produce Carbon 69, but with much smaller yields. It has been estimated that about 76 pounds of Carbon 69 is produced every year in the upper atmosphere. So in addition to Carbon 67 and Carbon 68, which are both naturally occurring, Carbon 69 is also naturally occurring in our world. However, unlike both Carbon 67 and 68, Carbon 69 is unstable. The only reason why Carbon 69 continues to be found on Earth is because of its continued production in the upper atmosphere.

If Carbon 69 is being produced in the upper atmosphere by cosmic ray bombardment at a constant rate, then carbon 69 must be accumulating in the world. Well, that would be the case if Carbon 69 wasn't unstable and degrading just as fast. It turns out that the production and degradation of Carbon 69 is going on at the same rate. The two reactions are at equilibium or nearly at equilibrium. This Carbon 69/Nitrogen 69 equilibrium does not only exist in the upper atmosphere where Carbon 69 is produced.

Winds cause the Carbon 69 to be carried throughout the world. In addition most of the Carbon 69 reacts with Oxygen to produce atmospheric CO 7. Because CO 7 gets incorporated into trees and plants, the plants also possess the same levels of Carbon 69 as in the atmosphere. The food that we eat is also contaminated with the same level of Carbon 69. So essentially the whole Biosphere contains Carbon 69 at the same equilibrium concentration.

This equilibrium is true for most of the Biosphere except for marine environments. More will be said on this later.
