A032600100016 (ERR-1,,10.) Uncertainty in the dead time losses. A032600100017 (ERR-S,3.,5.) The counting error at the 95.5% A032600100018 confidence level for 123Xe and 123I was less than 3%. A032600100019 For 125Xe(125I) the error was 5%. A032600100020 (ERR-2) Uncertainties in the irradiation parameters A032600100021 resulting from any lack of uniformity in the tellurium A032600100022 thickness, and specifically from heterogeneous A032600100023 distribution, if any, with time and place of the A032600100024 incident beam density.

A032600100042 The Xe-123 thick target production yields for the A032600100043 reactions were 6.44 mci/muAhr and 7.16 mCi/muAhr A032600100044 respectively, as compared to large 5 mCi/muAhr for A032600100045 the Te-122(a,3n)Xe-123 reaction.
