Many reports presented the conversion coefficients from air kerma to Hp(3) especially for photons but rare information with dose conversion coefficients for beta radiation. The dose equivalent quantities for assessment of the eye lens dose for photons and beta radiation must be considered separately depended upon with penetrating radiation and low penetration depth. Recently, Behrens (Physikalisch-Technische Bundesanstalt (PTB)) presented the correction factors for the ISO rod phantom, a cylinder phantom, and the ICRU sphere for reference beta radiation ﬁelds of the BSS2 which calculated from Sr-90/Y-90. In this study, the eye lens doses assessment in nuclear medicine were evaluated by correction factor of Hp(3)/Hp(0.07) calibrated with Sr-90/Y-90 using a cylinder phantom and ISO rod phantom respectively. Hp(3) for radionuclides used for nuclear medicine such as I-131, Tc-99m and Ga-68, were calculated from correction factor for eye lens dose from small OSL dosimeters inserted in a cylinder phantom at depth 3 mm. The results showed that percentage differences between evaluated eye lens dose from the correction factor compared with Hp(0.07) evaluated from extremities dose were found to be not exceeding ± 15%.
