  2. Tritium radioluminescence - Wikipedia

    en.wikipedia.org/wiki/Tritium_radioluminescence

    Tritium excretion can be accelerated further by increasing water intake to 3–4 liters/day. [11] Direct, short-term exposure to small amounts of tritium is mostly harmless. If a tritium tube breaks, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities.

  3. Radioluminescence - Wikipedia

    en.wikipedia.org/wiki/Radioluminescence

    Tritium is only a health threat if ingested or inhaled. Since tritium is a gas, if a tritium tube breaks, the gas dissipates in the air and is diluted to safe concentrations. Tritium has a half-life of 12.32 years, so the brightness of a tritium light source will decline to half its initial value in that time.

    Several fluorescent molecules can be used simultaneously (given that they do not overlap, cf. FRET), whereas with radioactivity two isotopes can be used (tritium and a low energy isotope, e.g. 33 P due to different intensities) but require special equipment (a tritium screen and a regular phosphor-imaging screen, a specific dual channel ...

  5. Luminous paint - Wikipedia

    en.wikipedia.org/wiki/Luminous_paint

    The fluorescent chemicals in fluorescent paint absorb the invisible UV radiation, then emit the energy as longer wavelength visible light of a particular color. Human eyes perceive this light as the unusual 'glow' of fluorescence. The painted surface also reflects any ordinary visible light striking it, which tends to wash out the dim ...

    en.wikipedia.org/wiki/Fluorescence_in_the_life...

    Fluorescence is widely used in the life sciences as a powerful and minimally invasive method to track and analyze biological molecules in real-time Some proteins or small molecules in cells are naturally fluorescent, which is called intrinsic fluorescence or autofluorescence (such as NADH, tryptophan or endogenous chlorophyll, phycoerythrin or ...

    Tritium activities are suspended while personnel gather information about the event, the report said. The lab plans to vent four barrels of tritium-laced legacy waste, releasing radioactive vapors ...

  8. Tritium - Wikipedia

    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 ...

  9. Liquid scintillation counting - Wikipedia

    en.wikipedia.org/wiki/Liquid_scintillation_counting

    Counting efficiencies under ideal conditions range from about 30% for tritium (a low-energy beta emitter) to nearly 100% for phosphorus-32, a high-energy beta emitter. Some chemical compounds (notably chlorine compounds) and highly colored samples can interfere with the counting process. This interference, known as "quenching", can be overcome ...
