Sapwood layers (the living xylem and phloem) are the tree s transportation system. The effect has been complicated by the addition of manmade radioactive carbon to the biosphere because of nuclear explosions and experimentation. Surely 15,000 years of difference on a single block of soil is indeed a gross discrepancy. TABLE 1 Effect of increasing Earth s magnetic field on Carbon 14 production in the upper atmosphere. Principal Methods of Measuring Radiocarbon There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry. This oxalic acid came from sugar beets in 1955.

Radiocarbon Dating Pioneer American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity. Radiocarbon dating has somehow avoided collapse onto its own battered foundation, and now lurches onward with feigned consistency. These effects would have contributed significantly to the long life spans the Bible gives the Pre-Flood humans. The new version will be released when this work is completed. The increased magnetic shielding of the earth s surface would also make life easier than it is today. Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis.

When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay. The water vapour canopy was one source of the rain during the Great Flood. The proton takes an electron with it and becomes an atom of hydrogen.
. Libby who first measured radiocarbon’s rate of decay and established 5568 years ± 30 years as the half-life. Another beam cut from heartwood formed in 1975 BCE (halfway to the centre of the trunk) would have a radiocarbon date of 11,510 BCE. Another possibility is that the upper water layer was totally separate from our normal atmosphere and suspended in a similiar manner to orbiting satilites.
