WebCertified Reference Material: Rare-Earth – Thorium Ore. OKA-2 was prepared from samples from a britholite deposit near Oka, Quebec. The britholite mineral has been described as thorium-bearing cerian silicate apatite. The samples were collected by the Radiation Geophysics Section, GSC in aid of an IAEA project to produce a gamma-ray ... WebThorium exists in nature in a single isotopic form – Th-232 – which decays very slowly (its half-life is about three times the age of the Earth). The decay chains of natural thorium and uranium give rise to minute traces of Th-228, Th-230 and Th-234, but the presence of these in mass terms is negligible. It decays eventually to lead-208. check this sentence for me https://americlaimwi.com
