Protactinium (Pa) is one of the rarest elements that can be found or extracted from the natural source. Protactinium can be found in soil, rocks, water, plants, and animals, but in a very low concentration. There are no uses outside of basic and experimental scientific research and no commercial applications for protactinium. 231 Pa is the most important natural isotope, while 223 Pa is the only artificial isotope. 231 Pa has become important to the scientists because 231 Pa/ 230 Th in the ocean can perform as an ocean circulation proxy. Because of its low concentrations, measurement of protactinium using thermal ionization mass spectrometry (TIMS) has become the finest and most promising technique.

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.
