Ionizing radiation sole cause of chronic myelogenous leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing radiation increases linearly with effective radiation dose at a rate of 5.5% per sievert. If this linear model is correct, then natural background radiation is the most hazardous source of radiation to general public health, followed by medical imaging as a close second. Other stochastic effects of ionizing radiation are teratogenesis, cognitive decline, and heart disease. The table below shows radiation
Treatment of infections after exposure to ionizing radiation 7–10 days. Exogenous infections can be caused by organisms that colonize the skin such as "Staphylococcus aureus" or "Streptococcus" spp. and organisms that are acquired from the environment such as "Pseudomonas" spp. Organisms causing sepsis following exposure to ionizing radiation: The management of established or suspected infection following exposure to radiation (characterized by neutropenia and fever) is similar to that used for other febrile neutropenic patients. However, important differences between the two conditions exist. The patient that develops neutropenia after radiation is susceptible to irradiation damage to other tissues, such as the gastrointestinal tract, lungs and the central nervous system.
