摘要：
An overview of the results obtained for atmospheric radon data at the Italian Antarctic research station of Terra Nova Bay (74 degrees 41 'S, 164 degrees 07 'E) is presented and compared with results obtained at the Brazilian station Ferraz (62 degrees 05 'S, 058 degrees 23. 5 'W) and at the city of Punta Arenas (53 degrees 08 'S, 71 degrees 53 'W), in the South of Chile. The results for the Italian Station suggest a greater contribution of local radon emanation from summer-exposed soils and rocks at this site, and a strong modulation by katabatic winds.
