The effort is essentially profitable only for blue topaz, colored diamonds and red tourmaline. The water has absorbed all the sugar it can. Some gemstones, such as zircon, are naturally radioactive. the gem name is the relative degree of radioactivity This process of irradiation can make the gems slightly radioactive. When you get right down to it, all food contains a small amount of radioactivity. First experiments to imitate these processes artificially were promising. After radon, there is a complex decay chain that ends up settling into some of the poisonous minerals we know today which are not radioactive, meaning they do not decay but are still harmful. If uranite was the main mineral from which the mine made its profit, then you probably would not be able to see this mine up close it would be blocked off well before the entrance. Radioactivity has never been measured in these light-colored blue topazes. Blue topaz irradiated with electrons shows lighter hues (trade name: "Electric Blue") and is not radioactive. Strong: (U) 48.27%, Barely: To state the obvious, the uranium in its chemical formula provides this radioactivity. (K) 6.69%, Barely: All gemstones that are made radioactive fall under NRC regulations.
