Abstract
Photon buildup for some SrSO4, BaSO4, MgSO4, MnSO4, FeSO4 and ZnSO4 thermoluminescent dosimetric (TLD) compounds was investigated in the present work. Photon energy absorption buildup factors and photon exposure build factors were computed for the TLD compounds using the five-parameter geometric progression fitting method in energy range 0.015–15 MeV for penetration depths up to 40 mean free path. The buildup factors were studied as a function of photon energy, penetration depth and chemical compositions. Effective atomic numbers and air-kerma for the TLD compounds were calculated and ICRU standard tissue equivalence was discussed.
