Lead, the isotope Pb 206.
You think probably at Ranger Uranium Mine (Northern Territory, Australia).
= 0.693 / T1/2 Nt = N0e(-lt)where N0 is the starting number of nuclei, Nt is the number of nuclei remaining after timet, l is the decay constant, and e = 2.718. The units for the decay constant would be s-1 (or sometimes expressed in disintegrations per second) if the half-life is expressed in seconds. This relationship expresses radioactive decay based on statistics and probability, from an examination of the behaviour of a large number of individual situations. Note that it does not give any indication when a particular nucleus will undergo decay, but only the amount of time needed for a certain proportion of the nuclei in the sample to decay.
