| Snag-free, 3-dot tritium sights and rustproof stainless steel construction round out a great carry gun. |
| Plutonium and highly enriched uranium and other heavy fissionable isotopes fall into this category, but tritium does not. |
| Unfortunately, tritium is a notorious and ubiquitous contaminant, and an impurity in deuterated acetone. |
| The optical sight works either by using ambient light or under low light conditions, from a battery or tritium insert. |
| If necessary, stocks of deuterium, tritium, hydrogen, and helium were supplied from on-board stores. |
| The three isotopes are sometimes known by the names of protium, deuterium, and tritium. |
