Tritium half-life t
Web1 day ago · However, the light can’t just last forever: Because tritium is radioactive, it has a half-life. A radioactive material’s half-life is the time it takes for half the material to decompose. As tritium radiates away its beta particles, what’s left is helium-3, which doesn’t glow. Tritium’s half-life is just over twelve years, meaning ... WebThe half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope. Consider the following example. Suppose we have 100.0 g of tritium (a radioactive isotope of hydrogen). It …
