Accumulation and Retention of Tritium
Introduction Tritium (3H) in the natural environment is derived from natural or anthropogenic sources and can be used to estimate human radiation exposure around nuclear fuel reprocessing facilities. Elevated concentrations of 3H in the environment are generally associated with its production at nuclear facilities and exposure of local populations can be a public concern. The concentration of c...
متن کاملTritium accumulation in structures of clay minerals
ABST RACT: Tritium accumulation in clay minerals (kaolinite, montmorillonite, palygorskite) was studied experimentally over a one year contact with tritiated water (initial activity 1.67610 Bq/m) under room conditions, and was compared to theoretical calculations. The amounts of tritium ions in bound water and structural hydroxyls were measured by the activity of water fractions released at cha...
متن کاملAdvanced Tritium Recovery System
LLE Review, Volume 89 25 Introduction As part of the U.S. Inertial Confinement Fusion Program, LLE plans to implode deuterium–tritium (DT)–charged microspheres. These microspheres are filled with high-pressure deuterium and tritium gas under cryogenic conditions. The spheres are then stored and transferred as needed to the target chamber (located in an adjacent room) under vacuum and at tempera...
متن کاملOrganically bound tritium.
Tritium released into the environment may be incorporated into organic matter. Organically bound tritium in that case will show retention times in organisms that are considerably longer than those of tritiated water which has significant consequences on dose estimates. This article reviews the most important processes of organically bound tritium production and transport through food networks. ...
متن کاملTritium Fact Sheet
General Information Tritium is the only radioactive* isotope of hydrogen and it is commonly represented by the chemical symbol H-3 or 3H. While the most common form of the hydrogen atom has a nucleus consisting of a single proton, tritium’s nucleus is comprised of three particles: two neutrons and a single proton. This configuration makes tritium’s nucleus unstable and tending to undergo a proc...
