Once called blueberries before the war, Radberries have rapidly evolved throughout the years. Blueberries barely survived the Great War and were saved due to the lack of damage to rural farms in Tennessee. Radberries have a unique effect of absorbing radiation and thriving on it much like ghouls. Known for their size (about as big as an apple) and taste, Radberries have become a popular treat for travelers of the wastes. Though high in nutritive and vitamins they are slightly addictive and cause increased aggression during withdrawal. The seeds of Radberries are large and have a juice that causes extreme tranquillization effects, thus it is common to see seeds found in the dung of Brahmin, Bighorners, and even humans.
