    en.wikipedia.org/wiki/Tritium

    Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...

    Hot water suits are loose fitting neoprene wetsuits used in cold water commercial surface-supplied diving. [34] A hose in the diver's umbilical line, which links the diver to the surface support, carries the hot water from a heater at the surface down to the suit. The diver controls the flow rate of the water from a valve near his waist ...

    en.wikipedia.org/wiki/Medical_gas_therapy

    The dry air on the Earth we inhale consists of 78.8% nitrogen, 20.95% oxygen and 0.93% argon. Heliox therapy is substitution of nitrogen with helium. Helium itself has no pharmacological value, it does not react in the body. Its only purpose is to make the flow less turbulent and help oxygen to get into the lungs.
