Radioactive Decay. Useful for calculating today's activity for any radioactive isotope. 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 ...

en.wikipedia.org/wiki/Tritium

Tritium (/ ˈ t r ɪ t i ə m / or / ˈ t r ɪ ʃ i ə m /) or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen.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 neutron.

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.

The maximum theoretical specific activity per tritium is ~29 Ci/mmol. So for this lot, the percentage of molecules labeled on three positions would be 78/87 = 89.7%. In reality, you need to look at the mass spectrometry analysis of this lot to see the ratio of S-adenosyl methionine with 0, 1, 2 and 3 tritiums.

As the decay directly produces a ground state helium nucleus, there is no excited state and hence no gamma emission. IN2P3. Tritium is a beta-emitting radioactive isotope of hydrogen. Its nucleus consists of one proton and two neutrons, making it three times as heavy as a hydrogen nucleus (with its one proton) and one-and-a-half times as heavy ...

where λ is decay constant; N is the tritium concentration in the groundwater and N 0 represents the sum of tritium and helium-3 concentrations in the groundwater. Since the tritium concentration of seepage water off Uwozu is 3.9±0.5 (T.U.), the spring groundwater gushing from the sea floor over 10 to 20 years, after having permeated the underground, was distinguishable by comparing it with ...

The fundamental law of radioactive decay is based on the fact that the decay, i.e. the transition of a parent nucleus to a daughter nucleus is a purely statistical process. The disintegration (decay) probability is a fundamental property of an atomic nucleus and remains equal in time. Mathematically this law is expressed as: dN = N dt (6.1) and N
