Abstract
The concentration of Th-232, Th-230 and Th-228 in various human tissue s of Japanese subjects obtained at autopsies are reported. The tissue samples were weighed, spiked with Th-234 tracer and ashed by acid. The solution was dried on a hot-plate. Separation of thorium radionuclide s was accomplished through cation-exchange resin chromatography and el ectrodeposition. ?he concentrations of thorium isotopes were measured by cr-spectrometry. Thorium-232 and Th-230, concentrations were found to be highest in lung, followed by bone. The maximum concentration of Th-228 was in bone. The lowest concentrations of thorium isotopes were in muscle.
