Quantifying organ dose to healthy organs during radiotherapy is essential to estimate the radiation risk. Dose factors are generated by simulating radiation transport through an anthropomorphic mathematical phantom representing a reference Indian adult using the Monte Carlo method. The mean organ dose factors (in mGy min^-1 GBq^-1) are obtained considering the microselectron ¹⁹²Ir source and BEBIG ⁶⁰Co sources in the uterus of a reference Indian adult female phantom. The present study provides the factors for mean absorbed dose to organs applicable to the Indian female patient population undergoing brachytherapy treatment of uterus cancer.This study also includes a comparison of the dimension of organs in the phantom model with measured values of organs in the various investigated patients.
