In plain language
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 two-dosemeter method overestimated dose.

What it found
Annualized eye lens dose projections for physicians approached the International Commission on Radiological Protection (ICRP) 20 mSv/year limit.
Key figures: up to 19.10 mSv/year
Five of eight physicians exceeded the IRPA investigation level for eye lens dose.
Key figures: 5 physicians > 6 mSv/year
Direct Hp(3) over the monitoring period (extrapolated to 12 weeks) was higher in physicians than in technicians.
Key figures: 0.58-4.59 mSv (physicians); 0.26-1.01 mSv (technicians)
The SSRPM two-dosemeter indirect method overestimated direct eye lens measurements.
Key figures: mean factors of 1.31 (physicians) and 1.68 (technicians)
Physician eye lens dose correlated strongly with fluoroscopy time.
Key figures: R2 = 0.918
Limits to keep in mind
Small sample (12 personnel, one Siemens Artis Zee system) monitored for 10 weeks, with extrapolation to 12 weeks and annual projections; abstract only, with no detail on eye protection use during monitoring.
