AB  - The beta(+)- emitting radionuclide Y-86g (t(1/2) = 14.7 h) forms a matched -pair with the beta(-)-emitting therapeutic radionuclide Y-90 (t(1/2) = 2.7 d) for theranostic application in medicine. Precise knowledge of the positron emission probability of the PET nuclide is very important, which was rather uncertain for Y-86g until recently. In this work, an Y-86g source of high radionuclidic purity was prepared and the positron emission intensity per 100 decay of the parent (hereafter "positron emission intensity") was determined by measuring the 511 keV annihilation gamma-ray using high-resolution HPGe detector. The total source activity was obtained from known gamma-ray emission probabilities. The electron capture (EC) intensity was also determined as an additional check by measuring the K-alpha and K beta X-rays of energies 14.1 and 15.8 keV, respectively, using a low energy LIPGe detector. From those measurements, normalized values of 27.2 +/- 2.0% for beta(+)-emission and 72.8 perpendicular to 2.0% for EC were deduced. These results are in excellent agreement with values recently reported in the literature based on a detailed decay scheme study.
