Skin contamination is one of the most likely risks after accidental or occupational radiological accidents. Using scintigraphy, we assessed a topical lotion for its decontamination efficacy (DE) exposure with short-lived medical radioisotopes technetium Tc 99m (99mTc) and thallium 201Tl (201Tl).Using 99mTc (300 ± 5 μCi/100 μl) (100 μl), thoracoabdominal region (shaved skin) Sprague Dawley rats human tissue equivalent were contaminated then decontaminated using cotton swabs soaked in formulated at different time intervals. Static counts recorded calculated DE. Histologic examination was performed on animal model.The DE formulation 85% 88% 2, respectively. The prepared effectively removed radionuclides from surface.The assisted effective removal radiocontaminants by decontaminating radionuclides. Moreover, minimal easily manageable radioactive waste generated this process. Further investigation regarding infusion into ready-to-use skin wipes self-decontamination may be useful mass casualty scenarios. (Disaster Med Public Health Preparedness. 2014;0:-).
