Abstract  

For determining low level lithium concentrations in water, a neutron activation method based on the measurement of tritium radioactivity produced by6Li(n,)3H reaction has been developed. This method is specific and free from interference by other chemical elements. Using a low background liquid scintillation counter for tritium measurement, the detection limit is approximately 0.3 ppm during irradiation at a thermal neutron flux density of 1.1·107n·cm–2·s–1 for 6 hours by a small nuclear reactor and liquid scintillation counting for 2000 minutes
