Illumination idea
Posted: 05 Oct 2019 06:34
This is just a rough sketch for a setting element. A series of large caverns is lit by naturally occurring "panels" in the walls, floor and ceiling, or maybe just some of them (just one wall, perhaps). The mechanism is that a large body of high grade radioactive material behind a thick wall of crystal, and the crystal acts as shielding, and also the gamma is absorbed and re-emitted, ultimately, as UV down through IR. I know it's wildly improbable, but am I neglecting some aspect that makes it impossible?
