Analysis of tritium releases to the atmosphere by a CTR [PDF]

, 1975
Removal by atmospheric processes of routinely and accidentally released tritium from a controlled thermonuclear reactor (CTR) was investigated. Based on previous studies, the assumed form of the tritium for this analysis was HTO, or tritiated water vapor.

Understanding Mass Spectrometry: From Ion Generation to Spectral Interpretation

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT This tutorial provides a structured introduction to mass spectrometry (MS), with particular emphasis on electrospray ionization (ESI)–based measurements. It is intended to support researchers from chemistry and related disciplines in developing a coherent understanding of MS principles, instrumentation, and data interpretation.

Density Functional Theory‐Based Investigation of Adsorption, Permeation, and Desorption of Hydrogen Isotopes in Fe–Cr Alloy of Varied Compositions

ChemPhysChem, Volume 27, Issue 14, 29 July 2026.
The energy profile of H from tetrahedral to a nearby tetrahedral void is changed with changes in Cr content. The diffusion coefficients of H are also found to vary with variation in the Cr content in the Fe–Cr alloy. These changes in energy and diffusion are due to the altered electronic interaction of hydrogen within the alloy matrix with varying Cr ...

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, Volume 600, Issue 14, Page 2028-2037, July 2026.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Calculation of tritium release from driver fuels into primary coolant of research reactors

Physical Sciences and Technology, 2019
Increasing of tritium concentration in the primary coolant of the research and test reactors during operation had been reported. To check the source for tritium release into the primary coolant during operation of the JMTR and the JRR-3M, the tritium ...

Advances in Human Mass Balance Studies: An IQ Consortium Perspective on Current Practices and Emerging Trends

Clinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 43-54, July 2026.
Human radiolabeled mass balance studies are crucial for comprehensively characterizing the absorption, distribution, metabolism, and excretion (ADME) of investigational drugs, providing essential data for drug development, regulatory evaluation, and product labeling.

Dose Delivered by Unit Amount of Tritium Released into the Environment [PDF]

Journal of Nuclear Science and Technology, 1997
Dose conversion values (DCV: Sv/kg-Tritium release) associated with a release of tritiated hydrogen (HT) to the atmosphere have been studied in the field experiment performed at Chalk River Laboratories in Canada in 1987. For a near ground-level release of HT, DCVs of 2×10−2 and 3×10−3 Sv/kg-Tritium were evaluated at distances of 100 and 400m on the ...

Improving the Reliability of Groundwater Recharge Estimates by Modelling Stable Water Isotope Transport in Soils

Hydrological Processes, Volume 40, Issue 7, July 2026.
Three 1‐D unsaturated zone models (HYDRUS‐1D with isotope fractionation) were calibrated with volumetric water content (θ) alone versus θ and δ18O δ2H from soil water. Adding isotopes constrains the parameter spaces and reproduces isotope profiles despite θ extremes, and reveals heterogeneous recharge in semi‐arid Tamil Nadu, South India.

Quantifying Groundwater Recharge With Cosmogenic Isotopes and a Hybrid Age‐Ranked Storage Selection Model in California (USA)

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Unsustainable groundwater depletion has led to the need for increased aquifer recharge operations, and improved quantification of recharge rates, particularly those that account for seasonally and annually variable recharge, reflecting changes in climate.

Sources of tritium in natural-technogenic systems

Geo&Bio, 2020
The radioactive decay of tritium is caused by the β-decay of one of the two neutrons in the nucleus of the hydrogen isotope atom (triton) into a proton, electron, and electron antineutrino with the formation of a monatomic gas and a half-life of 12.33 ...
