It´s presence in deep soils and minerals may be traced to the decay of radionuclides of the 238U decay chain 234Th>234Pa>234U>230Th>226Ra> 222Rn(3.82 d) >218Po The yields of γ-quanta with the energy of 73.9 keV, emitted by 234Pa nuclei produced by the β-decay of 234Th in uranium metal and uranyl nitrate matrices, differ by 26 ± 8%, which suggests the corresponding difference in the probability of the low-energy isomeric transition of 234Pa in these matrices.

58Ni. carbon-12. Expert Answer. The existence of an isomeric state at about 1360 keV in 234U, fed from 6.66h 234Pa(UZ) by a 730 keV transition followed by a 126 keV E1 y ray, was shown by Bjornholm and Nielsenl), who proposed a decay scheme in which a spin 5 isomer decays to the spin 4, 5 and 6 members of the yvibration band.
