Abstract  

In connection with the application of the uranium series method for the dating of fossil bones, separation techniques were developed for the isolation of uranium and thorium from a bone matrix. These separations were achieved on columns of the strongly basic anion exchange resin Dowex 1, using media of hydrochloric acid (for the isolation of uranium) and nitric acid (for the isolation of thorium). For uranium and thorium, yields of about 100% and about 70%, respectively, were obtained. The measurement of the α-activities was carried out following the electrolytic preparation of thin-layers of uranium and thorium on stainless steel discs. The α-spectrometry was done by means of Si-surface barrier detectors. Results are presented for a sample of snake-bones found in an Austrian cave.
