I don't know what the "most accurate . . . reference" is, but here are the
numbers from: Kocher, David. Radioactive Decay Data Tables. Technical
Information Center, U.S.Department of Energy. DOE/TIC-11026. Oak Ridge: 1981.

Th-234                                         Pa-234(Beta decay;
T1/2=1.17min)
L X-ray: 13.3keV 9.6%                   L X-ray: 13.6keV 0.44%
Gamma5: 63.29keV 3.8%               Ka2 X-ray: 94.665keV 0.115%
Gamma10: 92.38keV 2.72%            Ka1 X-ray: 98.439keV 0.187%
Gamma11: 92.80keV 2.69%            Gamma57: 766.41keV 0.207%
Gamma15: 112.81keV 0.24%          Gamma82: 1001.03keV 0.589%

Pa-234(IT decay; T1/2=1.17 min)
1 gamma @ 73.9keV 0.01%
