But who's going to bother with that? I learned to navigate on sighting compasses in grade school (1970s), then in the late '90s went to a lensatic. Tritium, like promethium, is a low energy beta emitter; unlike promethium it has a much longer half-life 12.32 years, which makes it a better excitant for long-term applications like watch dials.
