trit·i·um

 (trĭt′ē-əm, trĭsh′ē-)
n.
A rare radioactive isotope of hydrogen, H-3, having one proton and two neutrons in the nucleus and a half-life of 12.3 years, prepared artificially for use as a tracer and as a constituent of hydrogen bombs.

[From Greek tritos, third; see trei- in Indo-European roots.]

tritium

(ˈtrɪtɪəm)
n
(Elements & Compounds) a radioactive isotope of hydrogen, occurring in trace amounts in natural hydrogen and produced in a nuclear reactor. Tritiated compounds are used as tracers. Symbol: T or 3H; half-life: 12.5 years
[C20: New Latin, from Greek tritos third]

trit•i•um

trit·i·um

(trĭt′ē-əm, trĭsh′ē-əm)
A radioactive isotope of hydrogen whose nucleus has one proton and two neutrons and whose atomic mass is about 3. Tritium is rare in nature but can be made artificially in nuclear reactions. It is used in thermonuclear weapons and sometimes as a tracer. See more at hydrogen.

tritium

An isotope of hydrogen. Its nucleus contains one proton and two neutrons and thus has a relative atomic mass of three.
