Abstract

Yttrium-88 (T_1/2=106.6 d, I_β+=0.2% and I_ec=99.8%) is used in mixed gamma efficiency calibration standards and also as a substitute for ⁹⁰Y to quantify the biodistribution of Y-pharmaceuticals in animals. Yttrium-88 and strontium-85 as gamma emitting radiotracers were produced via ^natSrCO₃(p, xn) and ^natRbCl(p, xn) nuclear processes at AMIRS, with 18 and 15 MeV protons, respectively, at a current of 20 μA for 10 hours. The deposition of ^natSrCO₃ on the Cu backing was carried out by means of the sedimentation method. Yttrium-88 was separated in a 92 ± 5% radiochemical yield using the precipitation technique by precipitating ^natSr as SrSO4 (strontium-85 as a tracer) while radioyttrium passed through the filter paper. Also, a theoretical study of the nuclear reaction cross-sections for proton and deuteron induced reactions on ^natSr and ^natRb for the production of ⁸⁸Y and ⁸⁵Sr, respectively, was performed using the EMPIRE (version 3.1 Rivoli), TALYS-1.26 codes and the TENDL-2010 data base.
