In this paper, a new system to measure natural gamma-radiation in situ will be presented. This system combines a high-efficiency BGO scintillation detector with full-spectrum data analysis (FSA). This technique uses the (nearly) full spectral shape and the so-called 'standard spectra' to calculate the activity concentrations of 40K, 232Th and 238U present(More)
gamma-ray spectra of natural radionuclides are simulated for a BGO detector in a borehole geometry using the Monte Carlo code MCNP. All gamma-ray emissions of the decay of 40K and the series of 232Th and 238U are used to describe the source. A procedure is proposed which excludes the time-consuming electron tracking in less relevant areas of the geometry.(More)
The ever growing complexity of market processes continues to increase the importance of knowledge as the organization’s core capability to maximize business performance. Current conceptions of knowledge and knowledge representation, however, prove to be highly unproductive. A fundamental problem here is that insight into the nature of knowledge is an(More)
