Dating rocks and fossils using radioisotopes
Let’s say that a very heavy nucleus, such as a uranium nucleus weighing 235.0 AMU, splits (fissions) into two nuclei weighing 100.0 AMU and 133.9 AMU and a neutron (1.0 AMU).The 0.1 AMU of lost mass is converted to energy, according to Einstein’s famous equation, is huge.Stated another way, a very heavy nucleus sometimes splits, a process called particle of light).When fission happens spontaneously—without being hit—it is a type of decay., a type of decay, is beta decay in reverse; that is, an atom’s electron enters the nucleus, combines with a proton, and converts it into a neutron.Few scientists realize that on rare occasions heavy nuclei will decay by emitting a carbon-14 nucleus ( This calls into question the basic assumptions of the radiocarbon dating technique, especially when one understands the origin of earth’s radioactivity. " on pages 516–520.] Only about 65 naturally occurring radioisotopes are known.First, we need to understand a few terms concerning the atom.
The number of protons determines the chemical element; the number of neutrons determines the isotope of the element.
To contrast and evaluate two radically different explanations for the origin of earth’s radioactivity, we will first explain some terms.
With that background, new and surprising experimental evidence will become clear.
In an atom bomb, uranium or plutonium nuclei split (fission).
In a hydrogen bomb, hydrogen nuclei merge (fuse) to become helium.

For example, a deuterium (hydrogen-2) nucleus contains a proton and a neutron.
