H sub(p)(3) has been defined as the operational quantity for eye lens dosimetry. H sub(p)(3)/ka conversion coefficients were evaluated at the GSF (Germany) in a 30x30x15 cm super(3) 4-elements ICRU slab phantom for various energies and incident angles through Monte Carlo. The ISO report 12,794 suggests to employ a PMMA water filled phantom, of the same dimensions, for dosemeter calibration in terms of H sub(p)(3). The present paper briefly summarises the main aspects of a study carried out at ENEA-Radiation Protection Institute (Bologna, Italy) to provide practical procedures for the calibration of dosemeters in terms of H sub(p)(3). Tabulations of a new set conversion coefficients and air kerma backscatter factors are provided as a function of energy and incident angle. The paper demonstrates that a more accurate approach to the dosimetric assessment in terms of H sub(p)(3) could be rather simply introduced employing a reduced phantom.
