Abstract

The dose distribution in the ocular organs of nuclear medicine workers during the handling of diagnostic radionuclides was assessed via simulation in virtual space. The cornea and lenses received the highest dose, and the dose distribution tended to be proportional to the gamma-ray energy emitted from the radiation source being handled. Moreover, calculations on the dose-reduction effects of eyewear protectors for the eyes of the workers showed that the effects were inversely proportional to the emitted gamma-ray energy, with the dose-reduction effect decreasing in the order of 201Tl, 123I, 99mTc, 67Ga, 111In and 18F. Among the considered sources, the dose-reduction effect was significant for sources that emit relatively less energy, namely 123I, 201Tl and 99mTc, while it was lower for the remaining sources, namely 18F, 111In and 67Ga.
