Abstract:: |
Simultulnecus dctermination of thorium isotopes in human autopsy soft tissues, human bones, soil and rare earth ore dust is reported in this paper.The method consists of sample digestion, separation of thorium isotopes and electrodep05ition followed by alpha spectrometric measurement with a surface barrier detector. The contents of 232Th, 230Th and 228Th in each sample are determined simultaneously. In this method, 234Th is used as an internal racer for the correction of chemical recovery of thorium. |
