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 hydrogen.
A. Isotopes of Hydrogen
Protium (H) (99.985% natural
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.
