The article focuses on acquiring a 3D radiation map of a building via a two-phase survey performed with an unmanned aircraft system (UAS). First, a model of the stud-ied building is created by means of photogrammetry. Then, radiation data are collected using a 2-inch NaI(Tl) detector in a regular grid at a distance of 2 m from all accessible surfaces of the building (i.e., the walls and the roof)....
