A mobile gamma ray spectrometer system for nuclear hazard mapping: GAMMALOG v. 3.0
Smethurst, M.A.; Koziel, J.; Mogaard, J.O. (NGU-Rapport (2005.026), Report, 2005)The Geological Survey of Norway has developed a system for mobile gamma ray spectrometer surveying suitable for use in nuclear emergencies where potentially dangerous radioactive materials have been released into the ... -
A software tool to rotate spatial data on the surface of the sphere (Earth) for Geosoft's Oasis Montaj
Smethurst, M.A. (NGU-Rapport (2005.057), Report, 2005)Movement of the Earth's plates through geological time can be described in therms of a series of rotations on the sphere (Earth). If we can determine what these rotations have been, we can rotate ancient geological ... -

GammaLog Playback 1.0 - mobile gamma ray spectrometry software
Watson, R.J.; Smethurst, M.A. (NGU-Rapport (2011.051), Report, 2012)The Geological Survey of Norway (NGU) operates a mobile gamma ray spectrometer system which can be used in nuclear emergency situations to determine the location and type of orphan sources, or the extent and type of fallout ... -
GMAP - Geographic mapping and palaeoreconstruction package.
Torsvik, T.H.; Pesonen, L.J.; Smethurst, M.A. (NGU-Rapport (90.019), Report, 1990)In this account we describe GMAP, a combined palaeomagnetic database, geographic mapping and palaeoreconstruction package. GMAP is written for IBM AT compatible computers and the package contains approximately 1 Mbyte of ... -
Palaeomagnetism of the ophiolite complexes of Meldal, Sør-Trøndelag
Mac Niocaill, C.; Ryan, P.D.; Smethurst, M.A. (NGU-Rapport (95.115), Report, 1995)A palaeomagnetic investigation of the Early-Ordovician (middle to late Arenig) sheeted dyke complexes of Meldal has revealed a complex multicomponent magneti- zation history. Three components of remanent magnetization were ... -
Radiometric studies in the Meråker region: Environmental implications of anomalous levels of 137Cs
Walker, P.W.; Smethurst, M.A.; Niocaill, C. Mac (NGU-Rapport (92.327), Report, 1993)Airborne and ground-based radiometry surveys in the Meråker region have revealed unusually high concentrations of 137Cs in a bog to the north of Meråker. These anomalies were originally identified in Airborne Total count ... -
The distribution of 137Cs in the Meråker and Grong/Snåsavatnet Areas
Walker, P.; Smethurst, M.A. (NGU-Rapport (93.045), Report, 1993)Helicopter radiometric data collected over parts of Nord-Trøndelag between 1988 and 1991 have been reprocessed to produce maps of 137Cs fallout resulting from the reactor accident in Chernobyl. Backcalculated data indicate ... -
