Using Radiogenic Noble Gas Nuclides to Identify and Characterize Rock Fracturing [PDF]

Earth and Space Science
AbstractFracture‐released radiogenic noble gas nuclides are used to identify locations and constrain the volume of new fracture creation during subsurface detonations. Real‐time, in situ noble gases and reactive gases were monitored using a field‐deployed mass spectrometer and automated sampling system in a multilevel borehole array.

Development of non-destructive isotope measurement of the natural galena (PbS) using negative muon beams

Journal of Analytical Science and Technology
In Earth and planetary science, Pb isotopic composition is well known to play a key role in deciphering the origin and evolution of materials because they provide unique chronological and/or indigenous regional information as a radiogenic daughter ...

Present and Future Prospects of Radiation Therapy Using α-Emitting Nuclides

Dose-Response, 2018
Therapy with α-radiation has issues associated with internal exposure; its clinical use has been avoided. However, phase III clinical tests of the α-emitting nuclide 223 Ra on patients with cancer have been conducted, and results were reported in 2011 to

Upper mantle control on the W isotope record of shallow level plume and intraplate volcanic settings

Earth and Planetary Science Letters, 2022
Several studies have revealed small heterogeneities in the relative abundance of 182 W, the radiogenic nuclide of short-lived 182 Hf (t 1 / 2 = ∼ 9 Ma), in terrestrial rocks.

A Review of the Lunar 182Hf-182W Isotope System Research

Minerals, 2022
In recent years, the extinct nuclide 182Hf-182W system has been developed as an essential tool to date and trace the lunar origin and evolution. Despite a series of achievements, controversies and problems exist.

A Shorter 146Sm Half-Life Measured and Implications for 146Sm-142Nd Chronology in the Solar System [PDF]

Science, 2011
A New Lease on Half-Life Radiometric dating relies on measuring the abundance of long-lived radionuclides relative to the abundance of their radiogenic decay products—a process determined by the original radionuclide's half-life.

The Yellowstone magmatic-hydrothermal system: using radiogenic and stable isotope geochemistry to constrain the processes of water-rock interaction

, 2019
The hot springs of Yellowstone National Park provide a broad range of isotopic data (e.g. 238U-, 235U-, and 232Th-series) that can be exploited to interpret the geochemical processes occurring at depth, including water-rock interaction, nuclide sourcing,

The Effect of Radiogenic Heating on the Amino Acid Content of an Early Cometary Body

, 2013
This study compares the rates for the formation and destruction of amino acids in the liquid cometary core subjected to radiogenic heating by the β+ decay of the cosmogenic nuclide 26Al.
