The ratio of the weight of the titanium apron to a lead apron of the same size can be computed as the ratio of the density times the equivalent shielding thickness, i.e. ījurman B, Ahlgren L, Mattsson S (1982) Radiation dose to staff handling 99Tc m in hospitals.

A mobile shield combined with a nondisposable 1-mm lead equivalent patient apron (outside the primary beam) attenuates 98 of scatter. We conclude that reduced radiation use (e.g. Mobile shields of 0.5-mm lead equivalence can attenuate 95 of scatter radiation in the anteroposterior projection and 70 in the lateral projection. Use of robotic-guidance in a minimally invasive approach provided for a reduction of 62.5% of the overall radiation the surgeon was exposed to during open conventional approach. ![]() The 0.5 mm lead aprons blocked just over one third of the radiation scattered towards the surgeon. In the RO cohort, the average per-screw radiation dose and time were 51.9% and 73.7% lower, respectively, than the per screw exposure in the FA cohort. The radiation blocked by the aprons, represented as the ratio of the under-apron to above-apron TLDs, averaged 37.1% (range 25.4-48.3%, 95% confidence interval between 30.6-43.6%). Sixty four patients were included in this study, 34 in the RO cohort and 30 in the FA cohort. Outcome measures included the quantitative measurement of the surgeon's actual exposure to radiation, as recorded by thermo-luminescent dosimeters (TLD) worn both above and under the 0.5 mm thyroid and trunk lead protectors. Instrumentation was performed in either a robot-assisted, minimally invasive approach (RO) or a conventional, fluoroscopically-assisted, open approach (FA). Single-center, prospective, randomized study of adult patients with degenerative lumbar disorders, scheduled to undergo posterior lumbar interbody fusion. an equivalent thickness of at least 0.5 mm of lead at 100 kVp to restrict scattered. We quantified the level of their radiation blocking ability in a real-life setting. The shielding required to reduce radiation levels to within. Shielding by lead aprons is the most common protective practice. Despite the firmly established occupational risk of exposure to X-rays, they are used extensively in spine surgeries.
