Abstract
An airborne radiometric survey was initiated in central West Greenland in 1975 folIowing completion of the aeroradiometric work in East Greenland (Nielsen, 1972; Nielsen & Larsen, 1974). During, 1975 the region between Søndre Strømfjord and Jakobshavn Isfjord was covered, an area of c. 58 000 km2. The programme was carried out as a collaboration between GGU and the Danish Atomic Energy Commission's Research Establishment, Risø. GGU and Risø each supplied three participants. The aircraft, a Britten-Norman Islander, were chartered through Greenlandair Charter AIS. Aeromagnetic measurements were carried out simultaneously (Thorning, this report). Field operations were carried out from Søndre Strømfjord Air Base. It is planned to continue this radiometric survey duiing the next few years, including follow-up fieldwork on the ground.
