• Geometrical solid angle
• Geometrical efficiency
• Linear sources
• Circular disk detector

Knowledge of the geometrical solid angle is crucial in all measurements of the assets of radioactive materials and to calibrate detectors. A direct mathematical formalism for the determination of the geometrical solid angle and the geometrical efficiency of a circular disk detector and an arbitrarily positioned line source is deduced. The results have been linked with previous computational treatments. The comparison shows a very satisfactory agreement in all cases.
