Title: A new thorium-229 reference material

Abstract

A new reference material was characterized for ²²⁹Th molality and thorium isotope amount ratios. This reference material is intended for use in nuclear forensic analyses as an isotope dilution mass spectrometry spike. The reference material value and expanded uncertainty (k = 2) for the ²²⁹Th molality is (1.1498 ± 0.0016)×10^-10 mol g^-1 solution. The value and expanded uncertainty (k = 2) for the n(²³⁰Th)/n(²²⁹Th) ratio is (5.18 ± 0.26)×10^-5 and the n(²³²Th)/n(²²⁹Th) ratio is (3.815 ± 0.092)×10^-4.

Production of ${}^{229}{Th}$ for medical applications: Excitation functions of low-energy protons on ${}^{232}{Th}$ targets

Journal Article Griswold, Justin R. ; Jost, Carola U. ; Stracener, Daniel W. ; ... - Physical Review C

As a part of a general program to evaluate production routes for ²²⁹Th, we studied production of ²²⁹Th via proton-induced reactions on ²³²Th targets bombarded with low-energy protons, E_p ≤ 40MeV. The reported excitation functions include those for proton-induced reactions on natural thorium yielding to ^{228,229,230&232}Pa isotopes; ²³²Th(p,xn) reactions, where x=1, 3, 4, and 5, at proton energy ranges of 12–40 MeV. Although the data for ²³²Th(p,n)²²⁸Pa, ²³²Th(p,3n)²³⁰Pa, and ²³²Th(p,5n)²³²Pa reactions were deduced by direct analysis of the thorium foils after irradiation, the data for ²³²Th(p,4n)²²⁹Pa were obtained by radiochemical techniques. The half-life of ²²⁹Pa was evaluated and determined tomore »« less

Thorium-229 as an isotopic tracer for the radiochemical determination of thorium isotopes in biological samples

Journal Article Wrenn, M E ; Singh, N P ; Ibrahim, S A ; ... - Anal. Chem.; (United States)

The following three advantages make thorium-229 more desirable as an isotopic tracer in biological samples: (1) the increase in accuracy associated with simultaneous ..cap alpha.. spectrometric measurement of the tracer /sup 229/Th and the nuclides being determined /sup 232/ /sup 230/ /sup 228/Th; (2) the long half-life of /sup 229/Th compared with that of /sup 234/Th requires neither the repeated preparation and the associated time-consuming processes of purification and standarization, nor decay corrections; and (3) /sup 229/Th is an ..cap alpha.. emitter as are the isotopes to be determined, and the ..cap alpha.. spectrum provides a measurement of yield.

230Th-234U Age-Dating Uranium by Mass Spectrometry

Technical Report Williams, R W ; Gaffney, A M

This is the standard operating procedure used by the Isotope Ratio Mass Spectrometry Group of the Chemical Sciences Division at LLNL for the preparation of a sample of uranium oxide or uranium metal for {sup 230}Th-{sup 234}U age-dating. The method described here includes the dissolution of a sample of uranium oxide or uranium metal, preparation of a secondary dilution, spiking of separate aliquots for uranium and thorium isotope dilution measurements, and purification of uranium and thorium aliquots for mass spectrometry. This SOP may be applied to uranium samples of unknown purity as in a nuclear forensic investigation, and also tomore »« less

Internal standard method in {alpha} spectrometric determination of uranium and thorium radioisotopes using instrumental neutron activation analysis

Journal Article Byrne, A R ; Benedik, L - Analytical Chemistry (Washington)

A new approach to {alpha} spectrometric determination of the radioisotopes of uranium and thorium was developed for environmental samples based on {sup 238}U and {sup 232}Th as internal standards. {sup 238}U and {sup 232}Th were accurately determined in the sample by simultaneous instrumental neutron activation analysis. Other aliquots of the sample were totally dissolved, uranium and thorium separated by anion exchange, and thin sources electroplated for {alpha} spectrometry. From the known mass concentrations of {sup 238}U and {sup 232}Th, their activity concentrations were obtained, and thus from the relative ratios of uranium ({sup 234}U, {sup 235}U, {sup 238}U) and thoriummore »« less

Measurement of cross sections for the {sup 232}Th(P,4n){sup 229}Pa reaction at low proton energies

Journal Article Jost, C. U. ; Griswold, J. R. ; Bruffey, S. H. ; ... - AIP Conference Proceedings

The alpha-emitters {sup 225}Ac and {sup 213}Bi are of great interest for alpha-radioimmunotherapy which uses radioisotopes attached to cancer-seeking antibodies to efficiently treat various types of cancers. Both radioisotopes are daughters of the long-lived {sup 229}Th(t{sub 1/2} = 7880y). {sup 229}Th can be produced by proton irradiation of {sup 232}Th and {sup 230}Th, either directly or through production of isobars that beta-decay into {sup 229}Th. To obtain excitation functions, {sup 232}Th and {sup 230}Th have been irradiated at the On-Line Test Facility at the Holifield Radioactive Ion Beam Facility at ORNL.
