Uranium

An untouched Uranium Node doesnt give off Radiation. When a Miner is put on the Node the Radiation starts even when the Miner is unpowered. Radiation Radius is ~30m. Conveyor belts dont protect and the Radiation radiates from it making it a ~60 meter radiation zone around the transporting belt and storage. If you try to pick it up you will gain massive amounts of radiation until you drop it.
