The maximum dimensions for your carry-on bag are: Length - 24 (61cm) including wheels and handles ; Width - 17 (43cm) Height - 10 (25cm) For additional carry-on items beyond the one-bag limit, each piece will incur a fee. Refer to the checked baggage page for more information.
Tritium (3H) is the most stable radioisotope of hydrogen. That is, of all radioactive isotopes of hydrogen, tritium is the least radioactive. It has a proton and 2 neutrons in its nucleus. Tritium decays through beta minus decay and changes to helium-3. It has a half-life of 12.32 years.
Tritium is a weakly radioactive form of hydrogen, with a half-life of 12.3 years. The radiation emitted by tritium is not penetrating; it is a very low-energy form of radiation. About 99 percent of all tritium occurs in the form of tritiated water (HTO or DTO); see the explanation given below.ritium is a weakly radioactive form of hydrogen, with a half-life of 12.3 years.
