A mathematical gall bladder was added to the mathematical phantom and the specific absorbed fractions (PHI) were calculated for the 22 target organs (for the source in the gall bladder) by the Monte Carlo code. From these data and the /sup 99m/Tc decay scheme data, the S factors (rads per ..mu..Ci-day residence) for the organs when the source is in the gall bladder were estimated. From the reciprocity relationship for PHI, the S factors for the gall bladder when the source is located in any of the 22 source organs of the phantom were also estimated. The dose to the gall bladder wall from a single injection of the /sup 99m/Tc labeled scanning agent into man is estimated to be approx. 0.52 rads/mCi plus or minus about 1/2 this value depending on the assumptions in the estimation of this value.
