Ultra-High Vacuum (UHV) extraction methods for noble gases trapped in fluids inclusions

Tritiogenic contribution

Production of tritium in the atmosphere due to cosmic radiation or as a result of human activities, which may be military in nature (nuclear bomb explosion) or civilian (nuclear reactor). The emitted tritium (³H) is then produced by radioactive decay of ${}^{\mathrm{3}}\mathrm{H}\mathrm{e}$ with a half-life of 12.32 years.

White; Blank

Contamination levels observed in a UHV chamber using a protocol that is exactly the same as the one used to extract gases trapped in rock (e.g., duration, temperature, number of laser pulses).
