Web7 jan. 2024 · Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity. Like any radioactive isotopes, plutonium isotopes transform when they decay. Web13 apr. 2024 · Since the radioactive half-life of tritium is 12.4 years, holding the water in tanks for seven half-lives, about 85 years, would reduce the tritium content to less than 1 per cent of its current value. This option leaves the carbon-14 which would still roughly have the same radioactivity due to its 5,730-year half-life.

WebA more precise definition of half-life is that each nucleus has a 50% chance of living for a time equal to one half-life t1/2. Thus, if N is reasonably large, half of the original nuclei decay in a time of one half-life. If an individual nucleus makes it through that time, it still has a 50% chance of surviving through another half-life.

There are two types of uranium used for fuel in nuclear reactors, U-238 and U-235. The half-life of U-235 is 700 million years, while U-238 has a much larger half-life of 4.5 billion years. U-238 is the most commonly used, but surprisingly U-235 fissions the easiest.
