Occupational Radiation Doses to Operators Performing Fluoroscopically-Guided Procedures
Lens of eye and thyroid doses were much greater than effective dose; brain dose about 5 times lower than lens but still an order of magnitude above effective dose. (1.5 to 1300 μSv per case)

FAQ
Why do cataracts develop from occupational radiation?
The lens of the eye is highly radiosensitive due to its unique anatomy. The lens epithelium divides throughout life, and radiation-damaged cells accumulate in the posterior lens. Unlike most tissues,…

CRP Statement on Tissue Reactions / Early and Late Effects of Radiation in Normal Tissues and Organs, Threshold Doses for Tissue Reactions in a Radiation Protection Context
There are no established mitigators of radiation lens injury; some biological response modifiers give modest dose modification in other tissues. (DMFs 1.1-1.2, in a few cases 1.5-2)
