How Old Is the Earth: Radioisotope Dating - dummies
The article is in straightforward language and the non-technical reader could profitably work through it. Carbon 14 C or radiocarbon as it is often called, is a substance manufactured in the upper atmosphere by the action of cosmic rays. Ordinary nitrogen 14 N is converted into 14 C as shown to the right. Ordinary carbon is carbon 12 C.
