Anyone else have an obsession with Nite Glowrings?

I've always been a bit suspicious of carrying a highly toxic radioactive source around with me, no matter how small the quantities.

Someone once harvested tritium from gunsights in an attempt to build his own breeding reactor. All he got for his troubles was a nasty dose of radiation sickness.....

No, it was much more fun than that Wook,

great read that. Cheers Southey for digging it out. What a bright kid, sad that he never took it further

I believe he was told he could never work with nuclear materials again since he had already received more than a lifetimes dose.

I keep one on my dogs collar, great wee think for seeing where a black dog is in the dark

Been using them for a while, I clip one onto the corners of my tarp or onto the guylines

Holy thread ressurection!

Though in this case, here's why.

I just got 2 niteglow rings from http://www.niteglowrings.com/

Ice Blue & Orange minis.

Thing is although brand new, I think they're both DOA, I can't see *any* kind of glow whatsoever.

Do you need to do something to activate them?

Here's a picture of them in a dark place, no flash.



Although from very close up, and visible through the viewfinder I got this picture, although to the naked eye it's very faint, is this seriously how bright they get?

The effect is visually better in complete darkness but basicaly yeah, that's as bright as they get.
They are powered by atomic decay of a Hydrogen Isotope called Tritium, this is created in a nuclear reactor so "No User Servicable Parts" and cannot be refilled or recharged by putting them under a bright light.

They are indeed very good and get no reaction from a Geiger counter.

(I tried.)
