Tritium activity
WebApr 25, 2024 · Tritium, also known as 3H or H-3, is a form of hydrogen. In EXIT signs, tritium gas is contained in sealed glass tubes lined with a light-emitting compound. The tritium gives off low-energy beta radiation that causes the lining to glow. This type of radiation cannot penetrate a sheet of paper or clothing. WebDec 1, 2024 · Tritium is a common nuclide produced in PWRs. Three fission products of 235 U are the main source of tritium. A 1, 000 MW PWR produces 560–740 TBq of tritium by this means every year. In...
