Carbon 14 dating information
Cosmic rays enter the earth's atmosphere in large numbers every day.For example, every person is hit by about half a million cosmic rays every hour.This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.
The most common radioactive element in granite is Uranium-238.
Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.
When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.
