Radiusen

Radiusen is a term used as a proper noun in several contexts. In Scandinavian languages, Radiusen is the definite form of radius and is used to refer to the radius of a circle in mathematical writing. In Danish, Radiusen means the radius; in other Nordic languages similar forms exist. The word also appears as a surname in Nordic countries, though it is relatively rare and not widely documented in major name registries.

In fiction and media, Radiusen is occasionally used as a place name for towns or regions in imagined worlds. Such usages are author- or game-specific and do not correspond to a real-world geography.

Because there is no single, widely recognized entity named Radiusen, reference works typically treat it as a disambiguation term, pointing to the linguistic sense, the surname, and any fictional uses.
