A quantitative radiochemical method for the determination of the major sources of natural radioactivity in ores and minerals
January 1, 1953
The determination of Th232, Rn222, and Pb210 by isolation and subsequent activity analysis of some of their short-lived daughter products is described. The sulfides of bismuth and polonium are precipitated out of solutions of thorium or uranium ores, and the alpha particle activity of PO214. PO212 and PO210 is determined by scintillation counting techniques. PO214 activity is used to determine Rn222, PO212 activity for Th232, and PO210 for Pb210.
