You may also back decay sources to find out the original activity (or for any date), knowing the current activity. If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to perform the calculation.

Tritium (/ ˈ t r ɪ t i ə m / or / ˈ t r ɪ ʃ i ə m /) or hydrogen-3 is a rare and radioactive isotope of hydrogen, with symbol T or 3 H.The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 ("protium") contains just one proton, and that of hydrogen-2 ("deuterium") contains one proton and one ...

Tritium doesn't decay to another isotope of hydrogen plus an electron, that would violate charge conservation and baryon number conservation. You are also missing one decay product. I have no idea what you try to calculate in the bottom part. Comments (in English!) would help.

This free half-life calculator can determine any of the values in the half-life formula given three of the four values. The calculator can also convert between half-life, mean lifetime, and decay constant given any one of the three values. Learn more about how the half-life formula is used, or explore hundreds of other math, finance, fitness, and health calculators.

The above formulas are used in calculations involving the exponential decay of radioactive materials. This calculator can solve half life problems whenever three of the four variables are known: • time • half life • beginning amount • ending amount. There are four half life problems further down this page.
