Carbon 14 dating system

Carbon-14 can yield dates of only “thousands of years” before it all breaks down.Although many people think radiocarbon dating is used to date rocks, it is limited to dating things that contain the element carbon and were once alive (like fossils).In contrast, radiocarbon forms continually today in the earth’s upper atmosphere.And as far as we know, it has been forming in the earth’s upper atmosphere since the atmosphere was made back on Day Two of Creation Week (part of the expanse, or firmament, described in Genesis 1:6–8). Cosmic rays from outer space are continually bombarding the upper atmosphere of the earth, producing fast-moving neutrons (subatomic particles carrying no electric charge) (Figure 1a).1 These fast-moving neutrons collide with atoms of nitrogen-14, the most abundant element in the upper atmosphere, converting them into radiocarbon (carbon-14) atoms.Radiocarbon dating has permitted key moves in ancient times to be dated, for example, the last's end ice age, and the start of the Neolithic and Bronze Age in diverse locales.

These systems can permit dates up to 60,000 and at times up to 75,000 years before the present to be measured.The subsequent radiocarbon consolidates with barometrical oxygen to frame radioactive carbon dioxide, which is fused into plants by photosynthesis; creatures then procure 14C by eating the plants.At the point when the creature or plant passes on, it quits trading carbon with its surroundings, and starting there onwards the measure of 14C it contains starts to decrease as the 14C experiences radioactive rot.The thought behind radiocarbon dating is direct, however years of work were obliged to build up the procedure to the point where exact dates could be acquired.Examination has been progressing subsequent to the 1960s to figure out what the extent of 14C in the air has been in the course of the last fifty thousand years.
