In plain language
At one Chinese tertiary hospital, a hospital-wide multidisciplinary radiation protection management program was followed by lower recorded staff doses and higher training and dosimetry compliance among 510 radiation workers, though the uncontrolled before-after design limits causal conclusions.

What it found
Average annual effective dose per worker fell after the framework was implemented.
Key figures: 0.54 mSv to 0.34 mSv
Annual collective effective dose declined.
Key figures: 212.66 to 133.12 person-mSv
Fewer workers received annual doses above 1 mSv.
Key figures: 6.27% to 3.33% (P<0.001)
Training completion and certification rates rose.
Key figures: training 81.57% to 98.63%; certification 90.39% to 100% (P<0.001)
Personal dosimetry monitoring became universal.
Key figures: 92.75% to 100% (P<0.001)
Limits to keep in mind
Single-hospital retrospective before-after design with no control group, so secular trends or changes in workload or dosimetry compliance may explain part of the dose reduction; results are pooled across imaging, radiotherapy and interventional departments with no interventional-specific data in the abstract.
