Maximum Permissible Concentrations for Tritiated Water and Tritiated Thymidine

American Industrial Hygiene Association Journal, 1969
Abstract The electrons of importance biologically in the absorption of energy from beta particles emitted by tritium have energies below 1 keV. These electrons have extremely short ranges which prompt the examination of absorbed energy on some basis other than average dose, such as ergs/gm.

Tritiated Water Vapor Exchange in Sunflowers

Health Physics, 1983
Water vapor exchange between sunflowers (Helianthus annuus L.) and the atmosphere was studied in darkness and in light using THO as a tracer. In the presence of tritiated water vapor, the exchange of THO measured as tritiated water in the leaves was slower in darkness than under illumination.

Genotoxicity of tritiated water in human lymphocytes

Toxicology Letters, 1994
The present study was carried out to evaluate the genotoxicity of tritium, administered as tritiated water, in peripheral blood human lymphocyte cultures. Sister-chromatid exchanges (SCE) and chromosome aberrations (CA) were scored as genetic endpoints.

The labelling of proteins by irradiation in tritiated water

Biochimica et Biophysica Acta (BBA) - General Subjects, 1972
Abstract 1. 1. Tritium is irreversibly bound by myoglobin, S -carboxymethyllysozyme, lysozyme and wool during ultraviolet irradiation in the presence of tritiated water. In each case the main site of labelling, determined by radioassay of the amino acids liberated by enzyme hydrolysis, is the tryptophan residue.

Tritiated Water Space in Gastrocnemius of Rat

Nature, 1967
IF a muscle is heated at 105° C until its weight is constant, the loss in weight (70–80 per cent of the original weight) represents the total amount of water in the muscle. More refined methods of estimating water contained in the tissue—normally applied to a whole animal in vivo—have been evolved; these methods depend on the equilibration of a marker ...

Diffusion of Tritiated Water in Soils

Soil Science Society of America Journal, 1963
Abstract The apparent diffusion coefficient of tritiated water (D THO ) was measured in four soil materials and two sizes of glass beads at about 40% water content by volume, and in agar gel.

Infrared spectroscopy of tritiated water

Chemical Physics Letters, 2007
Abstract We report the infrared absorption spectrum of the OT stretch of 0.3% HOT in H 2 O. The absorption line shape has a peak at ω ∗  = 2121 cm −1 and line width of Δ ω  = 127 cm −1 (FWHM). Reduced mass scaling relationships for frequency, line width, and extinction coefficient are tested by comparing to ω OH and ω OD absorption spectra.

Tritium in Rabbits after Ingestion of Freeze-Dried Tritiated Food and Tritiated Water

Radiation Research, 1978
Three groups of rabbits were exposed to freeze-dried tritiated food and/or tritiated water(HTO) for 29 days in daily doses of 185 Bq per gram body weight. The first group was exposed to tritiated alfalfa, the second group received half of the daily dose in the form of tritiated alfalfa and half in the form of HTO, and the third group was exposed to HTO

Water-vapour counter for the measurement of tritiated water

The International Journal of Applied Radiation and Isotopes, 1968
Abstract A counter, filled with tritiated water vapour and heated at about 120°C, was operated successfully by using an electronic circuit which was desensitized for a period of several hundred μs following an input pulse from the counter (interruption time).

Synthesis of the JHPS International Symposium on Tritiated Water

Annals of the ICRP, 2021
As the decommissioning of Fukushima Daiichi nuclear power plant (NPP) progresses, the issue of how to deal with tritiated water has been attracting attention, both domestically and internationally. This article summarises the live discussion at the International Symposium on Tritiated Water, which was held by the Japan Health Physics Society (JHPS) in ...
