TL;DR: The ratio (235)U/(238)U was 0.007258 +/- 0.000016, in agreement with terrestrial uranium as mentioned in this paper, and the following upper limits were set: (236)U/238 U/(3 x 10(-9); parts per million of sample, (239)Pu.
Abstract: The abunldanzces of uranium and thorium were measured mass spectrometrically as 0.59 +/- 0.02 and 2.24 +/- 0.06 parts per million, respectively, in the fines of Apollo 11 builk sample. The ratio (235)U/(238)U was 0.007258 +/- 0.000016, in agreement with terrestrial uranium. The following upper limits were set: (236)U/(238)U
