(Forkortet) NGU has carried out new test measurements using av borehole gamma-ray spectrometer from IFG Corporation at different sites inthe North Charlotte Region. Improved calbrations of the instruments were made doing long term measurements on calibration pads at NGU. In situ calculations of K, U and Th content gave promising results as long as only one radionucleide was present. Calculating the K content in a situation where higher energy radiating elements were present, proved difficult.
The degree of saturation of groundwater with respect to a wide range of solid phases is calculated for 240 private and public bedrock wells in Akershus and Østfold counties, southeastern Norway. The samples were collected by the local Næringsmiddeltilsynene (Public Hygiene Control Office) in cooperation with the Geological Survey of Norway (NGU).

The airborne gamma-ray spectrometric method is primarily used for the detection of ore bodies, fallout from nuclear accidents and as a lithological mapping tool. Modern gamma-ray spectrometers can record at least 256 channels of data in the energy range 0-3 MeV. After applying concentional processing, there is still noise in the spectra. Several approaches are suggested to remove this remaining noise fraction (MNF).
The Norwegian mining and quarring industry had a turnover of approximately NOK 7 billion in 2001 and employed some 5200 workers. It is a major industry in some regions, and the most important counties are Nordland, Møre & Romsdal, Rogaland and Vestfold. The mining and quarring industry comprises companies engaged in extracting and processing minerals and rocks from bedrock or superficial deposits. Five categories of raw materials are distinguished: industrial minerals (e.g.

On 07 October, 1988, a helicopter radiometric survey was flown in the vicinity of Kragerø municipality. The purpose of the survey was to provide radiometric information to help assess radon hazard from radioavtive rocks in the area. A total of 60 line-kilometers of radiometric data were acquired in a single flight, covering an area of approximately 3 square km with a 50-m line spacing. The data were collected by The Geological Survey of Norway (NGU) personnel and processed at NGU.

A combined total of 2780 line-km of VLF, radiometric, and magnetic data were acquired using a nominal 200-m line spacing.
The report describes the cooperation between the Geological Surveys of Lithuania (GSL) and Norway (NGU) in the period 1992-96. GSL existed in 1992 primarily as an administrative body, governing the activities of state enter- prises which had existed prior to 1991.
The eclogite province of W.Norway is subdivided into 8 geographic regions. The three southernmost of these regions - Holsnøy, Dalsfjord and Førdefjord, are surrounded by large areas without known eclogites, while the regions from Nord-fjord and northwards form parts of a large eclogite province. The rutile content is generally 1-2%; 3-4% rutile or more occur within some eclogites in the Holsnøy (Hordaland), Dalsfjord and Førdefjord (both Sogn and Fjordane) regions.

Available information on bathymetry and seabed types has been compiled within the Havsul I-IV areas off Møre og Romsdal. Only a limited amount of detailed seabed information is available, and the main database for interpretation has been a regional, digital, bathymetric database with a grid size of 50x50 m. The main objective has been to interpret areas of exposed bedrock, as such information is of importance for the early planning for offshore wind energy parks.
This report presents geophysical interpretation results of gravity data as part of a project entitled ORMEL.

Catastrophic failure of large rock slopes in Norway has several times per century led to rock avalanches or large rock falls, which impacted into settlements directly, but also caused either a displacement wave when impacting a water body or damming of narrow valleys with often fatal consequences. Such events will also occur in the future.

In september, 1998, two helicopter geophysical survey were carried out over parts of Larvik and Porsgrunn municipalities. The purpose of the survey was to provide geophysical information to improve geological mapping in the area. A combined total of 3684 line-kilometres of VLF, radiometric, and magnetometric, and VLF data were collected in June, 1997, in a test area east from Larvik. The 1997 survey covered approximately 64 square km with a 100-m line spacing.
