However, each of them also occurs, to some extent, as primordial isotopes that were made in supernovae, rather than radiogenically as daughter products. The overall result is that radium is found at low and essentially unchanging levels in soils everywhere. Radium in the soil exhibits the same level of radioactivity as uranium from which it was originally derived, because of a natural phenomenon called secular equilibrium.

In other cores it appears as though a sudden deposition of low activity sediment has occurred on top of higher activity sediments, perhaps as a consequence of dredging or sediment transport. Since the excess Po activities depend directly on the value of the background Po activity, it is evident that only one level of background will yield a perfectly linear fit of the data.
