Abstract:

The demand for accurate and efficient tritium monitoring is growing rapidly as tritium has become one of the major radionuclides in the environment. Conventional methods based on liquid scintillation counting require long measurement time and tens of grams to kilograms of sample material, which limits the high-precision measurement of small-sized samples. To rapidly determine tritium concentrations from milligrams of sample material and therefore enable the accurate and efficient measurement of small-size environmental samples, accelerator mass spectrometry (AMS) is used for tritium determination. Hence, AMS tritium measurement is widely used in earth science, biomedicine, and radiation monitoring. In this paper, the basic principles and development history of tritium measurement by accelerator mass spectrometry are reviewed, and the preparation methods for tritium samples are introduced. The key researches and main applications of tritium measurement using accelerator mass spectrometry are also summarized, with a view on future developments in this area.

Key words: Accelerator mass spectrometry, Tritium, Organically bond tritium
