Standardization of Tritiated Water by Two Improved Methods
Applied Radiation and Isotopes, 2006Tritiated water has been standardized in the framework of a French-Romanian cooperation by two improved methods: liquid scintillation counting based on the triple to double coincidence ratio method and the internal gas proportional counting used in conjunction with a tritium generator for chemical reduction of water.

Damages of DNA in tritiated water
2022Tritium is a radioisotope of hydrogen emitting low energy β-rays in disintegration to 3He. DNA molecules are damaged mainly by β-ray irradiation, and additional damages can be induced by break of chemical bond by nuclear transmutation to inert 3He.

Tritiation of Animals from Tritiated Water
Radiation Research, 1972Mice were given tritiated water (HTO) to drink for 40-147 days at a specific activity of 94 ± 4.8 μCi/ml (mean ± SD). Tissue HTO was 77.8 ± 10.1 μCi/ml in liver, testis and intestinal mucosa, reflecting the input of H2 O in unlabeled food and metabolic H2 O. Bound T specific activity was 15.8 ± 6.0 μCi/g dry matter.

Advances in the Electrolysis of Tritiated Water
Nuclear Technology, 1988The exhaust plasma processing plant, proposed a few years ago as an alternative to the Tritium Systems Test Assembly plant in operation at Los Alamos National Laboratory, required further research in such areas as low liquid inventory electrolytic cell and the types of separator or membrane resistant to beta radiation.

An Accidental Intake of Tritiated Water
American Industrial Hygiene Association Journal, 1971Data on an accidental intake of tritium which resulted in about 400 mCi of tritium distributed throughout the body water of one man is presented. The urinary excretion and loss of tritium from blood were followed for a period of time which allowed a precise estimate of dose to blood and body tissues to be calculated.

Measurement of Tritiated Organic Compounds in the Presence of Tritiated Water in Urine
American Industrial Hygiene Association Journal, 1969Abstract A simple procedure is described for extracting tritiated organic metabolites from the urine by an alcohol-ether extracting solution. The extractant is evaporated to dryness, dissolved in alcohol, and analyzed for tritium. The procedure permits a separation of tritiated organic metabolites and other ether-soluble substances from tritiated water

This paper describes the preparation of a tritiated water standard and the absolute determination of its tritium concentration. It was realized that such standardization would have inherent difficulties due to the low P energy (1), the tendency of HTO to adsorb on surfaces (2), and the possibility of large isotope effects.

Maximum Permissible Concentrations for Tritiated Water and Tritiated Thymidine
American Industrial Hygiene Association Journal, 1969Abstract 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.
