Process of carbon 14 dating

Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative.

The main relative dating method is stratigraphy (pronounced stra-TI-gra-fee), which is the study of layers of rocks or the objects embedded within those layers.

The age of diamonds should be reduced to the approximate time of biblical creation—about 6,000 years ago.5 Old-earth advocates repeat the same two hackneyed defenses, even though they were resoundingly demolished years ago.

The first cry is, “It’s all contamination.” Yet for thirty years AMS radiocarbon laboratories have subjected all samples, before they carbon-14 date them, to repeated brutal treatments with strong acids and bleaches to rid them of all contamination.6 And when the instruments are tested with blank samples, they yield zero radiocarbon, so there can’t be any contamination or instrument problems.

Dendrochronology: Also known as tree-ring dating, the science concerned with determining the age of trees by examining their growth rings.

Half-life: Measurement of the time it takes for one-half of a radioactive substance to decay.

The age of the remains of plants, animals, and other organic material can be determined by measuring the amount of carbon-14 contained in that material.

Carbon-14, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays (invisible, high-energy particles that constantly bombard Earth from all directions in space).

Absolute dating methods are carried out in a laboratory.This method is based on the assumption (which nearly always holds true) that deeper layers of rock were deposited earlier in Earth's history, and thus are older than more shallow layers.The successive layers of rock represent successive intervals of time.Dating techniques are procedures used by scientists to determine the age of an object or a series of events.The two main types of dating methods are relative and absolute.

Yet carbon-14 has been detected in “ancient” fossils—supposedly up to hundreds of millions of years old—ever since the earliest days of radiocarbon dating.1 Even if every atom in the whole earth were carbon-14, they would decay so quickly that no carbon-14 would be left on earth after only 1 million years.
