238U decay chainalpha decaydecay datanuclear datahalf-livesNon-neutron nuclear data (half-lives, transition intensities, radiation energies and emission probabilities) have been re-evaluated for the radionuclides that constitute the decay chain of uranium-238 on the basis of new absolute measurements ...
This paper presents a simple method for determining the spontaneous fission decay constant (λ_f) of ~(238)U using a combination of CR-39 and diallyl phthalate (DAP) plates as solid-state nuclear track detectors (SSNTD). In this method, thin U-sources were prepared by depositing natural ...
The half-life for the decay of {sup 238}U to {sup 238}Pu has been measured to be (2.0{plus minus}0.6){times}10{sup 21} yr by chemically isolating and measuring from the resultant alpha particles the amount of plutonium that had accumulated in 35 yr from 8.4 Kg of purified uranyl ni...
decay chain (redirected fromDecay series) Encyclopedia Related to Decay series:uranium decay series decay chain n. A sequence of radioactive decay processes in which the decay of one element creates a new element that may itself be radioactive, and continuing until the sequence ends with stable,...

The behavior of the uranium decay chain nuclides and thorium during the flank eruptions of Kilauea (Hawaii) between 1983 and 1985 The concentrations of members of the {sup 238}U decay chain and {sup 232}Th have been determined for the lavas that erupted on the East Rift Zone of Kilaue.....
However, it needs a neutron moderator to help it sustain the chain reaction by slowing down the neutrons. This is due to the reason that the concentration of U-235 is very low in naturally occurring Uranium. Sometimes, control rods are also used for slowing down the whole process in ...
In fact, for the 232Th decay chain, the only gamma contribution above 2615 keV is given by the summing of this line with other gammas emitted in cascade. The probability of such a summing becomes negligible as the distance of the source from the crystal increases.Footnote 4 For the back...
