When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.This collision is less destructive than the initial collision that produced them.It will often work well with stones that have been heated by fire.The clay core of bronze sculptures made by lost wax casting can also be tested.Ideally this is assessed by measurements made at the precise findspot over a long period.

Radiocarbon dating has been one of the most significant discoveries in 20th century science.

BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.

What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?

Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials.

In contrast to relative dating techniques whereby artifacts were simply designated as "older" or "younger" than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.
