“…Raemmler et al (216) also discuss XRF yield measurements using an isotopic source and an HPGE detector. A unique RNAA procedure has been used to determine REE contents in monazites (217). The REE are fractionated on a column and the heavy rare earth fraction is counted separately to avoid interference from the highly enriched light rare earths.…”

“…Yb, and Lu) in irradiated samples after separation of the light REEs (LREEs) (i.e., La, Ce, Pr, Nd, and Sm). IDMS, though it provides highly precise results, cannot be applied to the determination of Pr, Ho, Tb, and Tm because they are mono isotopic (5).…”

The analytical results obtained by both methods were found to compare well with each other as well as with the results obtained by ICP-OES in the case of REEs, uranium, and thorium. However, in the case of zirconium, quantitative recoveries were obtained only with the fluoride fusion method. Though international monazite reference materials are available, certified or even probable values are not available for all the constituent elements. A certified monazite reference material, BGS: IGS-36 (British Geological Survey/Institute of Geological Sciences, U.K) was analyzed, and the results obtained are presented in this paper. The analytical results by both methods were found to compare well with each other and with the accepted values reported in literature for IGS-36. The %RSD for all the estimated elements varied from 1.0 to 4.0% at mg g-1 levels and from 5.0 to 15.0% at µg g-1 levels of concentration.

Radiochemical activation analysis is a more laborious analytical method than instrumental analysis, but can be used to determine elements at lower concentrations. In most cases, the sample to be analyzed is separated into groups of elements rather than individual elements, so that the elements do not interfere with one another during the measurement of radionuclides content. Schemes for separation into multielement groups are given for metals, biological, geological and environmental samples.
