英文摘要
I developed a method for very low-level tritium analysis of water samples. Duplicate water samples with different tritium concentrations were analyzed by both helium-3 ingrowth and conventional s-decay counting methods. The method compared equaling or surpassing conventional method with respect to detection limit, precision, time and effort for preparation. Tritium concentrations in surface seawaters collected from the Pacific Ocean were analyzed successfully.
