Uranium

Uranium is a new metal type in Minecraft, it is a radioactive metal that is very dangerous to collect as it causes the player to cause damage if they get too close.
To collect Uranium you must go below the layer 30 (Where gold spawns). Uranium is quite rare and it is extremely dangerous to collect.
Going within 5 blocks of uranium will damage you (half a heart every second). If uranium is between blocks while you are within the damage radius it will not damage you. Uranium Scrap (Basically ore but it’s called scrap) can be smelted into Uranium Ingot.
Uranium items (Everything made with uranium) will be radioactive meaning that if you have uranium items in your inventory you will take slow damage (Like starvation damage). Uranium items can be dropped into water to wash away the radioactivity, this will contaminate the water and make this water radioactive. Radioactive water does slow damage and it has a small green tinge to it.
Crafting Recipies
Uranium Generator: 8 uranium ingots surrounding a block of redstone. Provides a redstone signal within a 50 block radius even if not connected. Provides an infinite redstone signal making redstone repeaters useless around the uranium generator.
Bioscanner: 8 uranium ingots surrounding a block of lapis. Shows the location of mobs within a 100 block radius. The bioscanner can be upgraded further by surrounding the bioscanner in another 8 uranium ingots. This will increase the range of the bioscanner by 100 blocks. This can only be done 3 times.
Immunity Flask: 1 uranium scrap brewed in a brewing stand with a water bottle to make the Immunity flask. The flask makes you immune to all debuffs for 3 minutes (includes being on fire). Drinking the flask will give you the hunger debuff for one minute.
Totem Of Keeping: 4 uranium ingots placed in a cross without the top ingot. The totem can be placed in your inventory to protect you from losing your items after death.
