Report on effectiveness of protective deviced for staff in interventional procedures.

Jeremie Dabin, et al. Report of Euratom research and training programme under grant No 755523.

This study rigorously compared radioprotective drapes, head supported lead-acrylic face masks, lead head-caps, and Zero-Gravity, during clinical use with patients as well as phantom studies , and using Monte Carlo analysis.

Zero-Gravity reduced calculated annual exposure to the brain 6.9 X greater than head-supported lead acrylic face mask, and 10.3 X greater than radioprotective head-cap (Table 20). . Mask efficiency for eyes and brain depended greatly on model and orientation of head and imaging projection. The upward-directed incident angle of the radiation may enable its passage under the mask and cap, but not under the Zero-Gravity which seals to the apron at the bottom, and also provides more expansive coverage.

Drapes provided very little protection to the head, with “…dose reductions around 3% on average for the brain and the eye lens” and relatively low reductions elsewhere on the body which were highly dependent on imaging projection.

The authors concluded that “ZG offers a considerable dose reduction to all organs covered” [compared to the other tested methods].
