Incandescent Gas Lantern Mantles (2009)

Just for scale, Americans receive about 620 mrem per year, mostly from radon in the air.

Oh my God. This is hysterical. My hippie parents used a couple of these lanterns inside the house when I was a kid because something about being more natural. When in fact, they were dousing us all with radioactive gas. Awesome!

(The kerosene smoke wasn't an issue to them, of course, as they both smoked two packs a day. I'm sure they didn't notice it. I did of course. I can still smell it in my head.)

Ever wonder how seemingly normal, healthy people develop some random form of cancer? It's this sort of crap they did to us in the 20th century.

The light was so much brighter when they contained thorium. No real substitute has been found.
