This paper shows the calculation of the TDF of low and high dose rate intracavitary radiotherapy.  TDF from different techniques are also shown.  TDF for optimum therapy and a quick reference for high dose rate TDF are suggested.  For high dose rate the TDF at point B is 16.7% of point A and it is 20.8% in low dose rate.
