Regional Airborne Radiometric Surveys in Greenland 1975–1982

The dataset comprises regional airborne radiometric measurements acquired in Greenland during 1975–1982 as part of systematic geophysical mapping programmes. The measurements were collected using aircraft-mounted gamma spectrometers and record natural gamma radiation from potassium (K), thorium (Th) and uranium (U). The surveys covered large parts of Greenland and were conducted to support regional geological mapping and mineral exploration. The data constitute a historical geophysical reference dataset for analyses of near-surface lithological variations and the distribution of radioactive elements.

Purpose
The purpose of the dataset is to support regional geological mapping and mineral exploration by providing information on the distribution of naturally occurring radioactive elements in near-surface rocks. The data are used to identify lithological variations, structural patterns and areas with elevated concentrations of naturally occurring radioactive elements.

Supplemental Information
The dataset represents historical radiometric measurements acquired using instrumentation and processing standards of the time. Resolution and data quality depend on flight altitude, line spacing and instrument type applied during the individual surveys. The dataset is primarily suitable for regional interpretation and overview analyses.

Statement
The dataset is based on airborne radiometric measurements acquired during 1975–1982. Data were collected using aircraft-mounted gamma spectrometers measuring natural gamma radiation from potassium, thorium and uranium. The surveys were conducted as part of regional geophysical mapping activities and subsequently processed using standard corrections, including altitude correction, background correction and calibration against known reference areas. The digital dataset has been established based on the original measurements and associated survey documentation.
