Remarkably few gamma emitters have decay schemes sufficiently well established to manke good standards for accurate efficiency calibration. The absolute gammaemission rate for any isotope is not generally known better than plus or minus 5% probable error. From the extensive list of available gamma emitters, eight isotopes were selected on the basis of their established decay scheme, availability, half life, and convenience of radiation characteristics: cadmium-109, barium-133, tin-113, cesium-137, sodium-22, manganese-54, zinc-65, and cobalt-60. The method of calibrating each of these isotopes and the resulting data obtained on standard (NaI(Tl)l crystal scintillation counter setup are described. (auth)
