A cost-effective way to reduce the equivalent eye lens dose fromYttrium-90 radiopharmaceuticals.

Purpose: We analyzed the effect of the use of Eye Protective Equipment (EPE) and the best position to use individual dosimeters to estimate the eye lens radiation dose to a medical staff that works with yttrium-90.

Methods: Three Alderson-Head-Phantoms were exposed to 58MBq of Y for 24h, in two different experiments: (1) at different dosimeter placements and (2) with and without the use of EPE. The measurements were carried on by thermoluminescent technique.
