Radiactive dating

If there are multiple particles produced during a single decay, as in beta decay, their relative angular distribution, or spin directions may not be isotropic.

Decay products from a nucleus with spin may be distributed non-isotropically with respect to that spin direction, either because of an external influence such as an electromagnetic field, or because the nucleus was produced in a dynamic process that constrained the direction of its spin.

The nucleus may capture an orbiting electron, causing a proton to convert into a neutron in a process called electron capture.

All of these processes result in a well-defined nuclear transmutation.

It became clear from these experiments that there was a form of invisible radiation that could pass through paper and was causing the plate to react as if exposed to light.

At first, it seemed as though the new radiation was similar to the then recently discovered X-rays.

This decay, called spontaneous fission, happens when a large unstable nucleus spontaneously splits into two (or occasionally three) smaller daughter nuclei, and generally leads to the emission of gamma rays, neutrons, or other particles from those products.When the number of protons changes, an atom of a different chemical element is created.The first decay processes to be discovered were alpha decay, beta decay, and gamma decay.For a summary table showing the number of stable and radioactive nuclides in each category, see radionuclide.There are 29 naturally occurring chemical elements on Earth that are radioactive.
