Abstract

Solutions containing the potential radiotherapy radionuclide Lu-177 have been standardized at the National Institute of Standards and Technology (NIST) by 4 pi beta liquid scintillation (LS) counting with H-3-standard efficiency tracing using the CIEMAT/NIST method. Confirmatory measurements were made with 4 pi NaI(Tl) gamma -ray spectrometry. Activity determinations weremade on 4 solutions over the course of 10 months with an expanded (k = 2) uncertainty on the activity of 0.8%. Half-life measurements were carried out using the NIST "4 pi" gamma ionization chamber (IC) and LS counting and gave a new value of 6.65 +/- 0.01d, which is shorter than the current ENSDF-recommended value bq 1.3%. Impurity analyses were performed by high-purity germanium (HPGe) gamma -ray spectrometry and indicated only the presence ofLu-177m at a level of 0.02% that of the Lu-177 as of the respective reference times: for the four solutions. Calibration factors fur the NIST IC and Vinten 671 ionization chambers were developed, as were dial settings for the NIST-maintained Capintec CRC-12, Published by Elsevier Science Ltd.
