In plain language
Among 11 interventional cardiologists and fellows, dosimeters showed higher radiation on the left and center of the head than the right. A nonlead cap lowered measured dose to near background, though brain dose and health effects were not assessed.

What it found
Radiation exposure was significantly higher on the left and center of the cranium than on the right.
Key figures: 106.1 ± 33.6 mrad (left) and 83.1 ± 18.9 mrad (center) vs 50.2 ± 16.2 mrad (right); p < 0.001
After subtracting ambient radiation, outside-left exposure was 16 times the inside-left exposure and 4.7 times the outside-right exposure.
Key figures: 16 times; 4.7 times; p < 0.001
The nonlead XPF cap reduced dose under the cap to slightly above the ambient control level.
Key figures: 42.3 ± 3.5, 42.0 ± 3.0, 41.8 ± 2.9 mrad inside vs 38.3 ± 1.2 mrad ambient; p = 0.046
Center exposure outside the cap was 11 times that inside; no difference was seen on the right side.
Key figures: 11 times; p < 0.001
Limits to keep in mind
Small single-group study of 11 male operators using cumulative dosimeter readings on the cap itself, not on the head or brain; dose to the brain and any health outcome were not measured.
