The Effects of X-rays and Beta Rays (Tritium) on the Growth of \u3cem\u3eRickettsia mooseri\u3c/em\u3e and \u3cem\u3eRickettsia akari\u3c/em\u3e in Embryonate Eggs [PDF]
, 1960 The growth of Rickettsia mooseri was accelerated and quantitatively increased in embryonate eggs containing tritium oxide at levels of 180, 90, and 45 mc./egg during the growth period.

A broad-Band FT-ICR Penning TRap System for KATRIN [PDF]
, 2009 The KArlsruhe TRItium Neutrino experiment KATRIN aims at improving the upper limit of the mass of the electron antineutrino to about 0.2 eV (90% c.l.) by investigating the beta-decay of tritium gas molecules. The experiment is currently under construction to start first data taking in 2012.

The Generation and Analysis of Tritium-substituted Methane [PDF]
arXiv, 2023 An unavoidable category of molecular species in large-scale tritium applications, such as nuclear fusion, are tritium-substituted hydrocarbons; these form by radiochemical reactions in the presence of (circulating) tritium and carbon (mainly from the steel of vessels and tubing).

Direct Neutrino Mass Experiments
, 2016 With a mass at least six orders of magnitudes smaller than the mass of an electron -- but non-zero -- neutrinos are a clear misfit in the Standard Model of Particle Physics.

Assessment of molecular effects on neutrino mass measurements from tritium beta decay [PDF]
, 2015 The beta decay of molecular tritium currently provides the highest sensitivity in laboratory-based neutrino mass measurements. The upcoming Karlsruhe Tritium Neutrino (KATRIN) experiment will improve the sensitivity to 0.2 eV, making a percent-level quantitative understanding of molecular effects essential. The modern theoretical calculations available

Tritium Behavior from Vine to Wine
Applied SciencesThe hydrogen radioactive isotope, tritium, not only reflects seasonal variation in precipitation but also variations on a local level. To use this radioisotope in authentication and geographical indication procedures, the tritium levels in vines, grapes,

First Principles Study of Tritium Diffusion in Li2TiO3 Crystal with Lithium Vacancy
Materials, 2018 Li2TiO3 is one of the most significant breeder materials and has potential applications in future fusion reactors. Defect models with three types of lithium vacancies were considered to study the diffusion behavior of tritium in Li2TiO3 by the density ...

Laser-induced synthesis and decay of Tritium under exposure of solid targets in heavy water [PDF]
arXiv, 2013 The processes of laser-assisted synthesis of Tritium nuclei and their laser-induced decay in cold plasma in the vicinity of solid targets (Au, Ti, Se, etc.) immersed into heavy water are experimentally realized at peak laser intensity of 10E10-10E13 Watts per square centimeter.

Status of the KATRIN experiment with special emphasis on source-related issues [PDF]
arXiv, 2011 The Karlsruhe Tritium Neutrino experiment KATRIN will allow a model independent measurement of the neutrino mass scale with an expected sensitivity of 0.2 eV/c^{2} (90% C.L.) and so will help to clarify the role of neutrinos in the early universe is the direct measurement of the mass of the electron anti-neutrino.
