The aim of the present work is the development of logical dosimetry for human alimentary tract. In this work, specific absorbed fractions for both photon and electron to a stomach model with stem cells have been evaluated in the energy range from 10 keV to 4 MeV using Monte Calro simulation. Furthermore, S values to the stomach model have been evaluated for several positron sources: 
C, 
N, 
O and 
F. Consequently, it was found that photon SAFs to stem cells in the stomach are greater than those to the whole stomach wall. Electron SAFs to stem cells in the stomach were also found to be less than those used in the radiological protection. The stomach wall S values are less than those used in the radiological protection. It is concluded that the determination of target tissue in the stomach is very important for the SAF and S value evaluations.
