Carbon dating at
Radiocarbon then enters animals as they consume the plants (Figure 1b).
So even we humans are radioactive because of trace amounts of radiocarbon in our bodies.
Thermoluminescence dating, potassium-argon dating, amino acid dating, and archaeomagnetic dating can all help give us a window into a much wider span of time.
I appreciate you sharing all these helps and resources.
Since each beta particle represents one decayed carbon-14 atom, we know how many carbon-14 atoms decay during a month.
But those trace amounts were key to transforming our conceptions of the past.
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.
CARBON-14 IS CREATED (Figure 1a): When cosmic rays bombard the earth’s atmosphere, they produce neutrons.
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).
Rb)—are not being formed on earth, as far as we know.
