Eye lens dose of medical personnel involved in fluoroscopy and interventional procedures at a Malaysian Hospital
At one Malaysian hospital, eye lens doses measured near the eye in 41 fluoroscopy staff varied widely; primary operators and their left eye received the most, and kerma-area product (KAP) or…

Eye lens dose in interventional cardiology personnel in Vietnam: direct Hp(3) measurement, indirect method comparison, and fluoroscopy-time-based dose estimation
In 12 cath lab staff in Vietnam, projected annual eye lens doses for physicians reached up to 19.10 mSv, near the 20 mSv limit, and five physicians exceeded a 6 mSv investigation level. An indirect…

Eye lens dose correlations with personal dose equivalent and patient exposure in paediatric interventional cardiology performed with a fluoroscopic biplane system
Limits: Only two cardiologists at a single facility over one year, with frequent non-use of the ceiling shield, so the apron-to-eye ratio may not apply where shielding is used. Eye dose was estimated…

Development of radioprotective side shield attached to radioprotective glasses for reducing eye lens dose of endoscopists during endoscopic retrograde cholangiopancreatography: a phantom study
…light side shield clipped onto radioprotective glasses cut eye lens air kerma by roughly 40-90% compared with glasses alone. This is a dosimetry result; real-world comfort and use by endoscopists were…
