Stuart, T. P.

This memo addresses the problem of calculating detectability of discrete ..gamma..-ray sources as a function of ..gamma..-ray energy, detector size, speed of search platform, angular response of detectors, shielding between source and detector, temporal data processing techniques, and background contributions from natural ..gamma..-ray emitters in the environment. The equations are derived and the computer code described. The calculation method can be used with the Surveillance Accident Nuclear Detection System (SANDS), which contains two arrays of 20 each, 5-inch diameter by 2-inch thick NaI crystals, flown in a helicopter.
