Abstract:Radioisotopes are unstable nuclei of elements (eg Molybdenum 99), which are transformed into stable nuclei while
emitting radiation (particles, photons). This phenomenon is characterized as radioactivity. Radioactivity can be natural
or artificial. Artificial radioactivity is that observed in isotopes produced artificially in a laboratory. The study of
radioactive isotopes in combination with the development of systems for the detection of emitted radiation, was the
trigger for the investigation of possible ap… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
