Carbon 14 dating history
It begins by measuring the ratio of radioactive versus stable versions of an element.
Carbon dating works by basing an age calculation on the ratio of radioactive carbon (C) in the atmosphere before nuclear bomb testing to the same ratio in the sample. Using a formula that compares that ratio to a standard modern ratio produces a “percent modern carbon” (p MC) value that scientists use to estimate carbon ages for carbon-containing materials.
By 2100, a dead plant could be almost identical to the Dead Sea scrolls, which are more than 2,000 years old.”[xvi] Factor 10: Disequilibrium.
A critical assumption used in C in the atmosphere, it would take up to 30,000 years to build up to a steady state (equilibrium): “If the cosmic radiation has remained at its present intensity for 20,000 or 30,000 years, and if the carbon reservoir has not changed appreciably in this time, then there exists at the present time a complete balance between the rate of disintegration of radiocarbon atoms and the rate of assimilation of new radiocarbon atoms for all material in the life-cycle.”[xvii] Dr. Studies since Libby’s original work have shown the C is known to be 18.8 atoms per gram of total carbon per minute.

In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly discovered radioactive isotope of carbon.
Factor 4: Industrialization (past burning of coal).
It is widely accepted that the mass burning of coal during the industrial revolution released an enormous amount of C ratio before the industrial revolution, and modern carbon dating takes this into account by running experimental measurements through a calibration formula.[vii] But how do we know what the ratio was like thousands of years ago? The dating system hangs on these types of assumptions! Several studies have shown: 1) significant solar flares have occurred in the past, and 2) these flares have an impact on carbon levels in the atmosphere.
The cause of this difference is thought to be a solar flare, as the same signal is found in C in tree rings around the world, including Germany, Russia, the United States, and New Zealand.[x] Other researchers have noted similar findings.[xi] Do we know whether other solar flares like this occurred thousands of years ago? Heavy or light carbon atoms can become trapped, or at least concentrated, in “carbon reservoirs” where carbon isotopes do not quickly mix with the atmosphere.[xii] As a result, some modern deep ocean organics show a carbon age of 1,500 carbon years, for example.
The results of the study confirm that something is amiss:[xix] The British Science and Engineering Research Council (which funded the installation of the C14 apparatus at Oxford) ran a series of tests in 1989 with 38 laboratories involved worldwide. “The Influence of Fire on the Radiocarbon Signature and Character of Soil Organic Matter in the Siskiyou National Forest, Oregon, USA.” . For example, the Bristlecone Pines in California were dated to be 4,700 years old by counting the tree rings, which is within the age brackets of the Flood.
As a consequence, the council has insisted this year (1990) on new quality-control measures, by which checks are made with standard reference materials of known age. However, research conducted on the shows that seasonal effects can cause multiple rings (up to five) to grow in the same year.
While carbon dating can in fact return somewhat accurate ages for items that are a couple thousand years old (see discussion and endnotes below), too many evolutionary assumptions accompany carbon dates for items into the deeper past.
Several unknown factors can seriously impact carbon ratios.
Just a partial list of these factors includes: Factor 1: Forest fires.
