what exactly does the "no RAD" symbol on my PRS 50 stand for?? My understanding is that the luminous material does not contain radiation ahla the Panny Radomir???????????

Newer lume materials are based on chemical compounds that absorb light and then slowly release it. Other lumes were based on radium(before ~1970) and then later tritium both radioactive elements. Tritium still in use that what the T in T-Swiss-T markings means.

So that means the symbol is to denote a radioactive material "was" used or not??
