The various considerations necessary for conversion of the pulse height spectrum from NaI(Tl) spectrometers to photon intensity distributions are discussed. Some of these are: 1) resolution and efficiency of the crystal; 2) summing of cascade gamma rays; 3) source geometry and self-absorption; and 4) handling of positron emitters. A straightforward empirical method for subtracting the Compton distributions associated with the various gamma rays in a complex spectrum is indicated and the logical extension to continuous photon distributions is discussed.
