Radiological Training for Tritium Facilities
PROPERTIES OF TRITIUM - What is tritium?
Tritium is a radioactive isotope of hydrogen (H). Hydrogen is
the lightest and most abundant element in the universe.
Hydrogen has only one proton in its nucleus. Tritium has, in
addition to the single proton, two neutrons in its nucleus. This
makes it three times heavier than the most common form of
A. Isotopes of Hydrogen
1. Protium (H) (99.985% natural
2. Deuterium = hydrogen + 1 neutron
(D) (0.015% natural abundance)
Tritium = hydrogen + 2 neutrons (T)
Symbol for Tritium
Tritium is designated as:
T, H- 3, or 1 H
Chemical Properties of Hydrogen/Tritium
Tritium "behaves" just like hydrogen
chemically because it has one proton and one
electron like ordinary hydrogen.
