Abstract

A study of the sizes of so-called polonium radiohalos of various types found in biotite from Bancroft, Ontario, has been carried out. The evidence is consistent with the interpretation that these halos are variants of the standard uranium halos. A review of the literature indicates that there is no firm evidence that polonium halos exist, all evidence being equally consistent with the interpretation that these are uranium halos.
