Trivia

 * Considering the manner and abundance it occurs on Earth in real-life, this mineral should not be directly/harmfully radioactive. However, developer notes state that in future updates, it will harm the player when picked up if they are not wearing a Radiation Suit.
 * Uraninite Crystals were used to craft Uranium, which was removed in the Prison Update of 2017.
