(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.
