The sentence "One estimate of radiation exposure caused by wearing a watch painted with radium is 10-1000 millirads." is confusing: millirad is a dose, not a dose rate (dose per time). Thus, one would have to specify how long one must wear such a watch in order to absorb this dose. Andre.holzner (talk) 21:31, 28 August 2011 (UTC)[reply]

Replacement?

"radium dials have largely been replaced by tritium based light sources." What about phosphorescent light sources too? most normal watches only have phosphorescent glow, tritium watch faces don't seem common at all, and most other consumer products with glow is phosphorescence not radioluminescence, so it's surly just as much a replacement. — Preceding unsigned comment added by 83.100.195.46 (talk) 22:43, 15 April 2012 (UTC)[reply]
