Question

What does the term half life of tritium mean?

Answer 1

What is tritium?
Tritium is a radioactive isotope of the element hydrogen.
What are the properties of tritium?
Tritium is radioactive and has a half-life of about 12.5 years, which means that half of the radioactive atoms will decay naturally in that time. Although tritium can be a gas under controlled conditions, its most common form is liquid, because, like hydrogen, tritium reacts with oxygen to form water. Like ordinary water, water containing tritium, or tritiated water, is colorless and odorless. Of the three primary types of radiation, alpha, beta and gamma, tritium emits only beta radiation
