Question: A gamma point-source is made of 1 mCi Co-60. A detector, with an surface area of 2 cm^2, is placed at a distance of 2 m from the source. The detector exhibits a dead time of 1 ms and is best described with a non-paralyzable model. The measured count rate is 100 cps. What is the intrinsic efficiency of the detector? Hint: Use the simplified fractional solid angle equation.
