Tritium is a radioactive isotope of Hydrogen. Tritium light sources are radioluminescent and can be best described as a strong glow. They are self-powered and do not need to be charged via exposure to Bradley M. Sherrill. FRIB. Michigan State University. Facility for Rare Isotope Beams, FRIB Broad Overview.

Isotopes. Isotopes are atoms that have the same number of protons but different numbers of neutrons. Most elements in the first two rows of the periodic table have at least 2 isotopes with one being more common than the other. Lecture 30 . Beginnings.
