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.

In isotope geochemistry, our primary interest is not in dating, but using the time-dependent nature of isotope ratios to make inferences about the nature of reservoirs in the Earth and their evolution..

Radiometric Dating. A technique used to date materials such as rocks based upon a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products using known rates of decay.. 1.875.
