Sievert Sievert The sievert (symbol: Sv) is a derived unit of ionizing radiation dose in the International System of Units (SI) and is a measure of the health effect of low levels of ionizing radiation on the human body. The sievert is of importance in dosimetry and radiation protection, and is named after Rolf Maximilian Sievert, a Swedish medical physicist renowned for work on radiation dose measurement and research into the biological effects of radiation. The sievert is used for radiation dose quantities such as equivalent dose and effective dose, which represent the risk of external radiation from sources outside the
Treatment of infections after exposure to ionizing radiation mucositis and esophagitis suggest Herpes simplex infection or candidiasis. Either empirical antiviral or antifungal therapy or both should be considered. In addition to infections due to neutropenia, a patient with the Acute Radiation Syndrome will also be at risk for viral, fungal and parasitic infections. If these types of infection are suspected, cultures should be performed and appropriate medication started if indicated. Treatment of infections after exposure to ionizing radiation Infections caused by exposure to ionizing radiation can be extremely dangerous, and are of public and government concern. Numerous studies have demonstrated that the susceptibility of organisms to systemic infection
