In plain language
This narrative review reports that interventional cardiologists' heads can receive substantial lifetime radiation doses, linked in other studies to cataract, brain cancer and cerebrovascular disease, and that ceiling shields, curtains, eyewear and non-fluoroscopic methods can greatly reduce exposure.

What it found
Unprotected interventional cardiologists receive head doses up to ten times greater than chest doses under lead aprons, with the left brain hemisphere reaching up to 2 Sv over a professional lifetime.
Key figures: up to ten times; up to 2 Sv (equivalent to 10,000 chest X-rays)
Reviewed health effects of head exposure include cataracts, brain cancer, cerebrovascular disease, neurodegeneration and mood disorders.
Effects are described as established for moderate and low doses relevant to occupationally exposed cardiologists, not only high radiotherapy doses.
Key figures: moderate (100-1,000 mSv); low (< 100 mSv)
Suspended lead ceilings, curtains and specialized eyewear can reduce head exposure to near-zero levels.
In electrophysiology, non-fluoroscopic near-zero radiation approaches eliminate radiation exposure and relieve orthopedic stress.
Limits to keep in mind
Narrative review without systematic search methods described in the abstract; evidence partly extrapolated from other exposed populations, and causal language ("well-proven") reflects the authors' interpretation.
