How the Zero-Gravity radiation protection system protects interventionalists while potentially increasing their caseload and prolonging their careers.

1 mm Pb “apron” blocks scatter radiation far better than conventional aprons. 1 2 3 4 0.5 mm Pb acrylic head shield wraps around the front and sides of the head, reducing dose to eyes and head far better than lead glasses and mobile shields. 5 6 1 4 Arm flaps and low leg protection …

More confirmation of the perils of lightweight “lead” aprons.

Two recent manuscripts (by Fakhoury, et al and Lu, et al) highlight the reduced protection of non-lead aprons, the pervasive problems with labeling compliance and regulations in general, and why we often don’t know if we are shielded. Not all lightweight lead aprons and thyroid shields are alike (Fakhoury, et al. J Vasc Surg). Full …

Negligible radiation to head and eyes in a busy interventional practice, with no weight on the interventionalist.

By following some basic practices and using the Zero-Gravity, the radiation dose to the head and eyes of a busy interventionalist was only 8% above natural background. The manuscript also provides some brief information on how to maximally protect the head and eyes by adjusting the settings on the Zero-Gravity to best advantage. Occupational Eye …

This excellent study provides very sound confirmation of our own findings that attenuating head caps do very little to protect the brain due to their geometry relative to the scatter field. It also confirms older studies showing the poor lens protection provided by leaded glasses, especially to the contrateral (often the right) eye where it …

The Effects of Attenuation Properties and Back Coverage of Protective Clothing and Devices on Operator Exposures in the Interventional Suite

ABSTRACT: Many different personal radiation protection options are available today for use by interventionalists in their suites. This study examines a variety of options to determine the importance of lead vs. lead-free, back coverage vs. none, and frontal overlap vs. none. Secondary scatter was provided by a stack of acrylic (phantom patient) and exposure was …

Lightweight Aprons EXPOSED

Interventionalists are accustomed to extensive regulations in nearly all aspects of their field, and so are very surprised to discover that the protective quality of their lead aprons is very loosely regulated, resulting in great variation between similarly labeled products. Especially when buying a lightweight non-lead apron, they don’t know what they are getting without complicated …

Beware the “Lightweight Lead Apron”

Author’s note: This current discussion is intended to be relatively detailed with more specific citation support, and refers to the other link for practical recommendations. A relatively short and practical guide is available at this link: Link to “Lightweight Aprons Exposed” The regulations for testing and labeling of X-ray protective clothing are surprisingly lax (13, …
