I simply LOVE the way my teeth glow after eating a banana..
I understand that the radiation made it easier to light and gave better illumination with less flicker..
I don't think the low-level radiation made any difference to the illumination.
You can still buy thorium mantles on ebay.

;-) bon appetit !
Thoria is good for tube cathodes as well. Dunno if the two properties are related in any simple way.

Gas lights give a pale blue flame; this was made white by heating a ceramic or mineral glowing object; 'limelights' were based on lime (CaO), and the Coleman mantles of yesteryear were impregnated with thorium oxide (thoria) for it's durability at high temperature.
The melting point of thoria is 3300C.
Have you noticed that Nasa has lot more about tin whiskers there.
