摘要：

The detection of very low concentrations of tritium in the atmosphere requires rather large samples and counting times using conventional radioactive decay techniques. Substantial reductions in both sample size and counting time can be realized using accelerator mass spectrometry techniques. The authors have used the sector-focused cyclotron at the Naval Research Laboratory to detect tritium in hydrogen at the level of 1 part in 10**1**2 in a 4 ml sample of hydrogen at 1 atm pressure and 15 min counting time. The detection techniques as well as improvements in beam transport efficiency and elimination of memory effects in the accelerator will be presented.
