Abstract

This study assessed air-based decontamination methods for treating patients exposed to dry radiological contamination while minimizing reaerosolization during disrobing, particularly in extreme cold environments. A full-size manikin,  simulating an able-bodied Airman, was dressed in military-issue extreme cold weather gear and coated with 28 grams of Copper Oxide. The manikin underwent one of three treatments: HEPA vacuuming, a mobile personal air shower, or no treatment (control). After treatment, researchers removed the uniform and used optical particle counters to measure airborne dust concentrations that could pose risks during disrobing. Each method was tested ten times (30 trials total). Statistical analyses (ANOVA, Tukey’s test, and Steel-Dwass test) showed significant differences (p< .0001) between treatments and the control. HEPA vacuuming reduced airborne Copper Oxide by 84.4%, while the mobile air shower achieved a superior 97.3% reduction. The mobile air shower also had lower variation and a short one-minute cycle time, making it highly effective and practical for extreme cold environments. These results suggest mobile air showers could enhance decontamination, reduce risks to responders, and improve patient safety in demanding operational settings.
