Radiation Injuries

Severity of exposure can be estimated based upon time to emesis; survival is inversely related to radiation dose. Emesis that occurs greater than 4 hours after exposure typically predicts a more mild course of sequelae. Emesis within 2 hours predicts at least 3 Gy dose of radiation - Leslie Crosby MD

Radiation Injury and Emergency Medicine

Our understanding of toxicity associated with exposure to radiation has increased since the discovery of X-rays in 1895. X-rays were used to treat a variety of malignant and non-malignant diseases. The effects of radioactive exposure on specific tissues can vary. Radioactive particles destroy or impair tissue by generating free radicals that damage important molecular structures, such as DNA. Radiation exposure can lead to catastrophic consequences, ranging from severe, acute injury to long-lasting effects that manifest years after the initial exposure...

Exposure to radioactive particles is divided into intentional or unintentional causes. Notable intentional causes include the…
