cerium-144
radioisotope
Quick Summary
Cerium-144 is a radioactive isotope of cerium, a rare-earth metal. While naturally occurring cerium includes stable isotopes like cerium-140, cerium-144 is one of the many artificially produced radioactive isotopes of this element. Radioactive isotopes, like cerium-144, are characterized by their half-lives, which is the time it takes for half of the radioactive material to decay. Cerium-144 is noted for its use in industrial gauges and power sources.123
