Popis: Due to the recent new interest of the dosimetric community generated by evidence of larger number of induced cataracts for the same absorbed dose, in the frame work of the ORAMED project ( Oramed, 2008 ) a task was devoted to the critical revision of the eye lens dose assessment procedures. The present paper summarizes the Monte Carlo analyses carried out to optimize the H p (3,Ω) calculations in order to produce a set of conversion coefficients H p (3,Ω)/ K a as close as possible to those of the limiting quantity H T (eye lens)/ K a. Comparison were carried out with already published values calculated for a previous theoretical phantom, mainly suited for the calculations of H p (10,Ω)/ K a .
