The total neutron cross section of 228Th has been measured in the regions of 1.9 and 7.5 eV, with the Materials Testing Reactor (MTR) fast chopper. The 228Th occurred as a contaminant in several samples of the parent 232U, on which cross-section measurements were being made at various decay times. For the two resonances which grew in with enough prominence to allow analysis, the resonance parameters deduced are: 1. E0 = 1.896 ± 0.002 eV, Γγ = 36 ± 2 mV, = 0.57 ± 0.04 mV, 2. E0 = 7.55 ± 0.02 eV, Γγ = 70 ± 30 mV, = 0.44 ± 0.05 mV.
