EVALUATION OF NON-NEUTRON NUCLEAR-DATA FOR THE U-238 DECAY CHAIN

Non-neutron nuclear data (half-lives, transition intensities, radiation energies and emission probabilities) have been evaluated for the radionuclides constituting the decay chain of uranium-238. A selection of the many recommended data are presented that may be useful in several applications (e.g. environmental monitoring, radiation protection and dosimeter calibration). Some of the problems encountered during this evaluation are discussed, including assessments of the internal conversion coefficients, normalization factors and alpha-particle emission probabilities. © 1990.
