234Th – Comments on Evaluation of Decay Data by

Uranium, radium, and thorium occur in three natural decay series, headed by uranium-238, uranium-234, thorium-230, radium-226, and lead-210 in the case. Interferences from real and apparent betas that are emitted by other thorium isotopes and their progeny. For samples with low. 234Th/228Th activity ratios, we.

An assessment of particulate organic carbon to thorium-234

An assessment of particulate organic carbon to thorium-234 ratios in the ocean and their impact on the application of 234Th as a POC flux proxy. 25 May The isotope 234Th is daughter from 238U natural decay, with a half-life of 24.1 days. Then, 234Th produces 234Pa/234mPa pair, which decay. The decay chains of natural thorium and uranium give rise to minute traces of Th- 228, Th-230 and Th-234, but the presence of these in mass terms is negligible.
