Abstract

Thorium may be determined using a variety of analytical methods. These may be based on chemical or physical principles or may make use of the radioactive decay of the individual thorium isotopes. The method to be used for a certain analytical purpose is selected as a function of the matrix of the sample and of the concentration of thorium. The present paper describes different methodologies, their range of application and discusses selected results. The methods described cover a concentration range of more than twelve orders of magnitude, i.e. from concentrated solutions to micrometre-sized particles. Emphasis is given to active radiometric techniques, chemical and instrumental analysis.

This paper was presented as an invited lecture at the First European Workshop on the Analysis of Thorium in Workplace Materials, held at Mol (BE), 27 to 28 March 2001, and is published in the issue of 'Radiation Protection Dosimetry' that contains the proceedings of the workshop.
