Fission track analysis (FTA) is a direct technique to detect trace amounts of nuclides with high fission cross sections. To improve the capability of finding the exact location of contaminated particles in a sample, we have investigated combining alp

The dissolution characteristics of 232 Th from ThO 2 in the lung have been determined in an in vitro study. Two types of ThO 2 were examined to determine if the age of the material had any effect; an aged high-fired ThO 2 that had its progeny in secu

The determination of isotopic thorium by alpha spectrometric methods is a routine practice for bioassay and environmental measurement programs. Alpha-spectrometry has excellent detection limits (by mass) for all isotopes of thorium except 232Th due t
