Glow-in-Dark?
During WWII there was a substance available on Navy ships, in tape form, that one could place by light switches or other items one might want to locate in the dark (like a flashlight). This tape somehow absorbed light during the day, and at night gave off a faint glow, sufficient to be seen in a dark room. Is there anything like that available today - in either paint or tape form - that one can use for such purposes in the home? Thanks. -- ---------- CWLee Former slayer of dragons; practice now limited to sacred cows. Believing we should hire for quality, not quotas, and promote for performance, not preferences. |

My best friend has a old military radio with radioactive meter
markings, its very rare. He figures although it still glows hazards are long past. Might be worth a fortune. |

To be fair it should be noted that few if any people realized the danger. I would suggest that it is very likely that the military applications described by the OP were not the current products but were the radioactive ones. I can remember when consumer products (watches and clocks) had the radioactive materials. The military surplus Geiger counters would react to them. I also remember the X-Ray machines they had in shoe stores where they zapped poor kids (myself included) with large quantities of X-Rays to see if the shoes fit. We just did not know back then.

When I was a kid (circa 1950) Japan made the crap like China does
today. Our stuff was like Japan's stuff today (Ok, maybe not as reliable). Some of Japan's turn-around is credited to American statistician Dr. W.E.Deming who was invited there in 1951. |

I bought some glow in the dark paint from a homecenter going out of business. If I hadn't gotten 80% off I would have been real disapppointed. Whether any products are better I can't say, but the paint is useless. |

Radium should not be considered as glow in the dark since it actually
gives out light and is radioactive. Do light bulbs glow in the dark? Glow in the dark materials are those that absorb surrounding light and give out this light through a glow. This process is similar to photosynthesis and is what today's glow is all about. http://www.glowinfo.com/ |

They do as well although certainly wasn't the absolutely only factor, their consumer products weren't much until they began to pay attention to QA/QC.

unpurified radium glows in the dark too. Theres a cave in eastern PA
where guides would take you into a room and turn off ALL the lights. after a little time the cieling would twinkle. probably high in radon friends wonder if this cave has been closed for safety. Indians were very afraid of this and wouldnt enter it. |
