In plain language

In 1,457 monitored health workers in nine French hospitals, recorded under-apron doses were low and fell between 2009 and 2019, including in interventional radiology and cardiology. Nuclear medicine staff had the highest, stable doses. Eye and hand doses were not assessed.

What it found

  • Average whole-body dose among monitored health workers decreased significantly over 2009-2019, a 58% drop between 2009 and 2019 means.

    Key figures: -0.008 (95%confidence interval (CI) -0.010 to -0.005) mSv/year

  • Nuclear medicine workers had the highest exposure, which stayed stable over time; interventional radiology was second.

    Key figures: 0.36 mSv (0.33-0.39) nuclear medicine; 0.20 mSv (0.17-0.23) interventional radiology

  • Radiologic technologists and physicians were the most exposed professions, with decreasing exposure; nurses had lower mean doses.

    Key figures: 0.15 mSv (95%CI 0.14-0.16) technologists; nurses 0.05 mSv

  • The share of nonzero recorded doses fell from 38% in 2009 to 20% in 2019.

    Key figures: 38% to 20%

  • Overall mean dose was low, with only one annual dose above the 20 mSv limit, in a surgery department in 2014.

    Key figures: OM = 0.10 mSv, 95%CI 0.10-0.11, max = 24.74

Limits to keep in mind

Retrospective registry data from a single chest dosimeter worn under the apron, with doses below 0.05 mSv recorded as zero and possible non-wearing of dosimeters; workers who changed jobs were excluded, and no eye, extremity or health outcome data were analysed.
