In plain language
Tunisian radiology and cardiology hospital workers had higher rates of chromosome damage markers in blood cells than matched unexposed people. This is a biomarker association, not proof of disease or cancer risk in individuals.

What it found
Chromosomal aberration and micronucleus frequencies were significantly higher in radiation-exposed hospital workers than in matched controls.
Exposed groups comprised 30 radiology and 30 cardiology department workers, compared with 27 age- and sex-matched healthy controls.
Key figures: 30 radiology, 30 cardiology, 27 controls
Authors interpret the increase as a potential cytogenetic hazard and call for safety programs.
Limits to keep in mind
Small cross-sectional biomarker study with no individual dose data or effect sizes reported in the abstract; job roles and confounders such as smoking are not described.
