>at least until recently
Has something changed? I know tritium sources are on the decline, but it always tickled my mind that radioactive lume was available to consumers for reasonable prices.
- CamperBob2 6y agoHaven't heard of it being used recently, except perhaps in gunsights, but a quick Google search brings up quite a few tritium-illuminated watches at moderate prices. I would've guessed that button-activated LED backlighting would have replaced it by now. Edit: interestingly, Wikipedia says that radium was still used in watches until 1970.
