The spectral analysis of simultaneously observed photons in separate detectors may provide an invaluable tool for radioisotope identification applications. A general recursive method to determine the activity of an isotope from the observed coincidence signature rate is discussed. The method coherently accounts for effects of accidental coincidences within a single detector and detection efficiencies. A verification of the approach with computer simulations is also discussed.
