摘要

Thorium is a naturally occurring element for whom all isotopes are radioactive. Many of these isotopes are alpha emitting radionuclides, some of which have limits for inhalation lower than plutonium in current regulations. Neutron activation analysis can provide for the low-level determination of ~(232)Th but can not determine other isotopes of dosimetric importance. Biological and environmental samples often have large quantities of materials which activate strongly, limiting the capabilities of instrumental neutron activiation analysis. This paper will discuss the application of a combined technique using alpha Spectrometry and radiochemical neutron activiation analysis for the determination of isotopic thorium.
