In plain language
Among the most exposed cardiac cath lab staff in a Tuscan dosimetry databank, cumulative doses (median 46 mSv over 10 or more years) corresponded to a modeled lifetime cancer risk of about 1 in 192. This is an estimate, not observed cancers.

What it found
For the 15 workers with at least 10 consecutive years of dosimetry records, the median estimated lifetime attributable risk of fatal and nonfatal cancer was about 1 in 192.
Key figures: 1 in 192 (interquartile range = 1 in 137-1 in 370)
Median cumulative individual effective dose among the 15 workers with long dosimetric histories was 46 mSv.
Key figures: 46 mSv (interquartile range = 24-64)
Cath lab staff made up two-thirds of the workers in the regional databank with yearly exposure above 6 mSv.
Key figures: 67% of the 6 workers with yearly exposure >6 mSv
Authors conclude cumulative occupational exposure is associated with a non-negligible lifetime attributable cancer risk for the most exposed cath lab staff.
Limits to keep in mind
Cancer risk is a model-based projection (BEIR VII) from under-apron dosimeter readings, not observed cancer cases; the sample is small (26 workers selected, 15 with long records analysed for risk) and selected for higher exposure, from a single regional databank.
