Pulse-height spectra recorded by a passive spectral gamma-ray logging system were simulated by radiation-transport calculations for several combinations of gamma ray sources and tool environments. Derived from the calculated log responses were (1) source- and energy-dependent environmental corrections and (2) calibration factors and an environmental correction method for three-window potassium/uranium/thorium analysis.
