WebSep 12, 2024 · The half-life (T1 / 2) of a radioactive substance is defined as the time for half of the original nuclei to decay (or the time at which half of the original nuclei remain). The half-lives of unstable isotopes are shown in the chart of nuclides. WebThe formula for the half-life is obtained by dividing 0.693 by the constant λ. Here λ is called the disintegration or decay constant. Hence the formula to calculate the half-life of a substance is: t1 2 = 0.693 λ t 1 2 = 0.693 λ. Where, t1 2 t 1 2 = half-life. λ = constant. morley ale house perth
