The carbon-14 in their bodies breaks down to nitrogen-14 and escapes at the same rate as new carbon-14 is added. CARBON-14 IS DEPLETED (Figure 1c): When an animal dies the carbon-14 continues to break down to nitrogen-14 and escapes, while no new carbon-14 is added.By comparing the surviving amount of carbon-14 to the original amount, scientists can calculate how long ago the animal died.
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.
Through photosynthesis carbon dioxide enters plants and algae, bringing radiocarbon into the food chain.
Radiocarbon then enters animals as they consume the plants (Figure 1b).
CARBON-14 IS CREATED (Figure 1a): When cosmic rays bombard the earth’s atmosphere, they produce neutrons.
These excited neutrons then collide with nitrogen atoms in the atmosphere, changing them into radioactive carbon-14 atoms.carbon 12 13 and 14 are the three isotopes of carbon.All carbon atoms have 6 protons but the number of protons can vary.Iodine-131 has proved effective in treating hyperthyroidism.Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. The most well-known of all the radiometric dating methods is radiocarbon dating.Because the rate at which this activity decreases in time is known, the approximate age of the material can be...
