Uranium, A New Effect, And a New Biome:

There is now a rare new biome called the "Radioactive Caverns", where you can find tougher variants of zombies, skeletons, and creepers. These new varients give a new effect when they attack, "Irradiated". The irradiated effect can lower your maximum health over time, give nausea, and cause blindness, unless wearing the hazmat suit. In this new biome, you will find a large amount of uranium ore, which gives the irradiated effect when touched, carried, and in the water you swim in. It needs a diamond pickaxe to break and drops 1-3 Yellowcake Powder.
