The Separation of Tritium Radionuclide from Environmental Samples by Distillation Technique
Tritium is an isotope of hydrogen which emit beta particles in energy range of 5 – 18,6 keV, and has relatively long half life of 12.3 years. In the environment, tiritum is originated both from the nature and human activities. Naturally, tritium is produced in the atmosphere by interaction of cosmic rays with the nuclei of atoms present in the air, and estimated to contribute the annual effecti...
متن کاملImpact of tritium discharged from a research reactor on concentrations in environmental water samples
A b s t r a c t . T h e d is tr ibut ion of environmental tritium concentrat ions in several samples taken near the K y o t o U n i v e r s i t y Research Reactor (KURR) was studied. The KURR Institute (KURRI) supports three major sources o f trit ium: a D 2 0 (heavy water) fac i l i ty and a Cold Neutron Source ( C N S ) fac i l i ty in the K U R R conta inment , and a tritium target fabricate...
متن کاملMeasurement of extremely (2) H-enriched water samples by laser spectrometry: application to batch electrolytic concentration of environmental tritium samples.
RATIONALE Natural water samples artificially or experimentally enriched in deuterium ((2) H) at concentrations up to 10,000 ppm are required for various medical, environmental and hydrological tracer applications, but are difficult to measure using conventional stable isotope ratio mass spectrometry. METHODS Here we demonstrate that off-axis integrated cavity output (OA-ICOS) laser spectromet...
متن کاملObservation of Tritium in Gas/plasma Loaded Titanium Samples
The observation of significant neutron yield from gas loaded titanium samples at Frascati in April 1989 opened up an alternate pathway to the investigation of anomalous nuclear phenomena in deuterium/solid systems, complimenting the electrolytic approach. Since then atleast six different groups have successfully measured burst neutron emission from deuterated titanium shavings following the Fra...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
