In plain language

In a small single-centre study of two physicians performing cardiac catheterizations, non-lead 0.35-mm Pb-equivalent aprons blocked about 98.5% of chest scatter dose, similar to lead aprons, and were reported as more comfortable.

What it found

  • The non-lead 0.35-mm Pb-equivalent apron combined a high shielding effect with good comfort.

    Key figures: 98.5% shielding

  • The lead 0.35-mm apron shielded best but was rated least comfortable because it was heaviest.

    Key figures: 98.9% shielding; comfort very poor

  • The non-lead 0.25-mm Pb-equivalent apron was most comfortable but had the lowest shielding effect.

    Key figures: 96.1% shielding; comfort excellent

  • Shielding of the non-lead and lead 0.35-mm Pb-equivalent aprons was very similar.

  • Mean external dose tended to be lower in procedures with non-lead aprons, likely because an additional lead acrylic shield was used more often in those procedures.

    Key figures: non-lead 142.6 or 123.9 μSv vs lead 166.4 or 209.2 μSv

Limits to keep in mind

Only two physicians in about 50+ cardiac catheterizations at one Japanese centre, with apron choice left to physicians, no statistical analysis, and comfort assessed informally by interview; use of an additional shield was uncontrolled.
