Uranyl Nitrate

Uranyl Nitrate (UO8N2) is a solid material that appears during the uranium treatment process. It forms when dirty Uranium Tetrafluoride interacts with Nitric Acid. It can be placed as a wall that will glow green if you will target an ultraviolet beam on it. But placing it as a wall is a bad idea because it is very toxic and pretty radioactive too. You can get Nitric Acid and water by smelting it in the furnace at a temperature of 100°C. Can be dissolved in Acetone, but not in water or benzene.

It is planned to add a new function to this material: boosting negative effect at the photo, but photography isn't implemented yet.
