title: Efficacy of common decontamination methods for cleaning contaminated wounds.
abstract: Emergency preparedness and response for work with hazardous materials, including radiological materials, necessarily have to involve injuries sustained by the workers. Removing radionuclide contamination from wounds in tissue is essential to minimizing the intake of radiological materials and the internal dose to the individual. This study compares the efficacy of common decontamination methods for removal of Co from contaminated wounds inflicted in pig tissue. The decontamination procedures investigated include a commercially available, non-prescription, surfactant-based, non-ionic wound cleanser spray; a physiologic saline solution spray; and a physiologic saline solution pour. Three different types of wounds are examined: smooth incision, jagged cut, and blunt force trauma wounds. The cleanser and saline sprays are more effective at decontaminating all three wounds than the saline pour. Within the statistical limitations of the study, the difference between the cleanser spray and the saline spray is not significant. However, the cleanser spray successfully decontaminates the wound to a lower mean value. The most noticeable impact in the decontamination process appears to be due to the spray pressure employed with the cleanser and saline sprays.
