Fission exceeds absorption in the range of 1 - 5 million electron volts (MeV). Nubar, the number of neutrons emitted per fission, ranges between 2.5 and 3 in the relevant energy range. You can compare uranium 234 with known nuclear explosives and prove it to yourselves.

[quote="Michael C. Emmert"]Hello, stinkysox77;Michael C. Emmert wrote: it's very easy to tell if a sample of uranium is U-238 or U-234. The alpha particle released by U238 has an energy of 4.26975 million electron volts (MeV). The alpha particle released by U-234 has an energy of 4.8598 MeV.
