Crystal Structure Analysis of Thorotrast in Biopsied Liver and Thorotrast Solution

Abstract

Specimens were prepared from biopsied human liver sample and thorotrast solution.
The molecular form of the thorium was analyzed by a selected area-diffraction method. Debye-Scherrer rings coincided with those of thorium dioxide, except for an unidentified ring of weak intensity.
These results indicated that thorium deposited in human tissues exits mainly as a form of its dioxide.
