Measurement 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 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 radium-226 concentration and dose calculation of drinking water samples in Guilan province of Iran
Background: Radium-226 (226Ra) is a product of the 238U radionuclide decay series that significantly incorporated into the human body through water intake. It can also potentially cause a series of health problems including cancers of the digestive system. Radium-226 (226Ra) is a product of the 238U radionuclide decay series that significantly incorporated into the human body through water ...
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...
