About Nuclear Half-Life
Time and transition. Use isotopes half-lives to calculate remaining quantities, total time elapsed, or the decay constant.

Remaining Mass (g)
29.829
Decays: 70.2%
λ: 1.2097e-4 yr⁻¹
Lab Standard: Radioactive decay follows first-order kinetics. This means the time required for half the atoms to decay is independent of the starting amount.
