In plain language
In ten interventional radiologists and cardiologists followed for three years, chest dosemeter readings tracked eye-lens and hand doses fairly closely. Conversion factors differed by specialty, so estimates from chest badges are a stopgap, not a substitute for dedicated eye and extremity dosimetry.

What it found
Whole-body chest dosemeter readings correlated moderately to strongly with eye-lens and extremity doses.
Key figures: r = 0.86-0.91, R2 = 0.73-0.83
The eye-lens conversion coefficient was higher in cardiologists than in the radiology group, supporting group-specific coefficients.
Key figures: 1.8 vs 0.68
Most variance was within-operator rather than between operators.
Key figures: inter-operator 20%-25%; within-operator 75%-80%
Conversion coefficients varied substantially, reflecting heterogeneous exposure conditions.
Key figures: CV ~30% for k1, 27% for k2
Limits to keep in mind
Retrospective analysis of only ten operators at what appears to be a single programme, with large within-operator variability; the abstract does not report shielding use or the country.
