METHOD
Over 12 weeks, with real patients and a full clinical team, researchers ran six randomized weeks with MasterPeace in place against six weeks with conventional shielding, mapping cumulative radiation dose using 69 body-worn dosimeters across the upper and lower body for both the primary operator and the scrub nurse. All results were normalized to each patient’s actual radiation output, so the findings reflect what our shielding achieves rather than differences in case mix or procedural complexity.

RESULT
SUBSTANTIAL REDUCTIONS: ONLY A FRACTION OF ANNUAL OCCUPATIONAL LIMITS 

The extrapolated values presented in the study are based on an annual volume of 800 procedures, reflecting a high-throughput interventional programme and results; a great fraction of the EU’s 20 mSv and the USA’s 50 mSv annual occupational limits.  Per procedure: 1.3 microSV (0.13 mrem) for the Primary Operator and 0.7 microSv (0.07 mrem) for the Scrub Nurse.
