    A logical complement to tritium is its stable decay product He method in lakes was done by Torgersen et al. These authors showed that physical-limnological processes such as gas exchange, vertical turbulent diffusion, oxygen depletion rate and mass flux rates in general can be quantified by the use of this tracer pair.

    Although the method proved promising, its use in physical limnology remained scarce.

    The analysis of cosmogenic nuclides in the form of helium and beryllium isotopes from volcanic rocks allows for an estimation of the time when the rocks were exposed at the Earth's surface for the first time.

    General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime.

    In particular, the is directly related to the energy and momentum of whatever matter and radiation are present.

    LLNL has developed a noble gas mass spectrometry facility that houses a state-of-the-art water-gas separation manifold and mass spectrometry system designed specifically for high throughput of groundwater samples. scientists with cutting-edge expertise in the measurement and interpretation of noble gases and tritium in groundwater.

    The fully automated, computer-controlled manifold system allows analysis of the full suite of noble gases (3He/4He, He, Ne, Ar, Kr, and Xe concentrations), along with low level tritium for reporting of derived quantities that include tritium/helium-3 groundwater age, noble gas recharge temperature, and dissolved excess air concentration.
