Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...

[citation needed] In Australia products containing tritium are licence exempt if they contain less than 1 × 10 6 becquerels per gram (2.7 × 10 −5 Ci/g) tritium and have a total activity of less than 1 × 10 9 becquerels (0.027 Ci), except for in safety devices where the limit is 74 × 10 9 becquerels (2.0 Ci) total activity.

Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero.
Assuming a density of 114 grams per cubic metre (0.192 lb/cu yd) at $100/l helium-3 would be about a thirtieth as expensive as tritium (roughly $880 per gram ($25,000/oz) vs roughly $30,000 per gram ($850,000/oz)) while at $2000/l helium-3 would be about half as expensive as tritium ($17,540 per gram ($497,000/oz) vs $30,000 per gram ($850,000 ...
Oxygen-15 is a radioisotope, often used in positron emission tomography (PET). It can be used in, among other things, water for PET myocardial perfusion imaging and for brain imaging. [ 20 ] [ 21 ] It has an atomic mass of 15.003 0656 (5) , and a half-life of 122.266(43) s .
In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [ 1 ] and it is corrosive due to self- radiolysis . Diluted, tritiated water is mainly H 2 O plus some HTO ( 3 HOH).
Oxygen-18 (18 O, Ω [1]) is a natural ... It can also be used to make an extremely heavy version of water when combined with tritium (hydrogen-3): 3 H 2 18 O or T 2 ...
