How to radioisotope dating
Radioisotopes are an essential part of radiopharmaceuticals.
Some radioisotopes used in nuclear medicine have short half-lives, which means they decay quickly and are suitable for diagnostic purposes; others with longer half-lives take more time to decay, which makes them suitable for therapeutic purposes.
Also used to irradiate fruit fly larvae in order to contain and eradicate outbreaks, as an alternative to the use of toxic pesticides. Used to trace sand movement in river beds and on ocean floors, and to trace sand to study coastal erosion.
Also used to trace factory waste causing ocean pollution, and to study sewage and liquid waste movements. Nuclear medicine uses small amounts of radiation to provide information about a person's body and the functioning of specific organs, ongoing biological processes, or the disease state of a specific illness.
Different isotopes of the same element have the same number of protons in their atomic nuclei but differing numbers of neutrons.
Radioisotopes are radioactive isotopes of an element.
