What is a Disease? Close observation and frequent FBE with differential. Acute Radiation Syndrome, also known as radiation toxicity or radiation sickness, is an acute medical condition caused by irradiation of the whole body (or a significant portion of the body), by a high dose of penetrating radiation in a short period of time, generally minutes. Illnesses collectively called “acute radiation syndrome” occur within a few hours to months after exposure to high-dose radiation (from approximately 1-2 Gy to 10 Gy). Bogdan I Gerashchenko R.E. Chicago : Year Book Medical Publishers, Inc.; 1989. To receive email updates about this page, enter your email address: Centers for Disease Control and Prevention. Symptoms varied with the severity of exposure but often included fatigue, nausea, vomiting, and hair loss. It follows a somewhat predictable course and is characterised by signs and symptoms that are manifestations of cellular deficiencies and the reactions of various cells, tissues, and organ systems to ionising radiation. Precisely record all clinical symptoms, particularly nausea, vomiting, diarrhea, and itching, reddening or blistering of the skin. Also, more information can be obtained from the CDC Health Alert Network at emergency.cdc.gov or by calling (800) 311-3435. From Andrews GA, Auxier JA, Lushbaugh CC. This fact sheet is for clinicians. There are different types of Acute Radiation Syndromes which develop depending on doses of radiation, and these syndromes vary in time scale and mortality. Examples for syndromes: Down’s syndrome, Parkinson’s syndrome, Acquired Immune Deficiency Syndrome, Cervical Syndrome, Cushing’s syndrome, Restless legs Syndrome, Scalded Skin Syndrome, Toxic Shock Syndrome, Yellow-Nail Syndrome, Acute Radiation Syndrome etc. Berger ME, O’Hare FM Jr, Ricks RC, editors. The radiation that causes ARS is large in dosage, which means greater than 0.7 Gray (Gy) or 70 rads; penetrates the body and reaches the internal organs; and affects the entire body or at least a great portion of it. Common radiation exposures to low dosage of radiation like CT scans or X-rays do not cause ACS. In most cases, healing occurs by regenerative means; however, very large skin doses can cause permanent hair loss, damaged sebaceous and sweat glands, atrophy, fibrosis, decreased or increased skin pigmentation, and ulceration or necrosis of the exposed tissue. ARS, or radiation sickness, occurs in humans after whole-body reception of large doses of ionizing radiation delivered over a short period of time. In addition to the blood samples required to address the trauma, obtain blood samples for CBC (complete blood count), with attention to lymphocyte count, and HLA (human leukocyte antigen) typing prior to any initial transfusion and at periodic intervals following transfusion. Due to the severity of this disease, the World Health Organization (WHO) recommends that manipulation of active viral cultures of SARS-CoV be performed in containment laboratories at biosafety level 3 (BSL3). Call the Radiation Emergency Assistance Center/Training Site (REAC/TS) at (865) 576-3131 (M-F, 8 am to 4:30 am EST) or (865) 576-1005 (after hours) to record the incident in the Radiation Accident Registry System. If a patient is known to have been or suspected of having been exposed to a large radiation dose, draw blood for CBC analysis with special attention to the lymphocyte count, every 2 to 3 hours during the first 8 hours after exposure (and every 4 to 6 hours for the next 2 days). Acute radiation syndrome (ARS), colloquially known as radiation sickness, is a rare yet often fatal set of symptoms that accompanies abnormally high exposure to ionizing radiation. Subsequently the RT were characterized chemically and biologically. Thank you for taking the time to provide feedback. The radiation causes cellular degradation due to damage to DNA and other key molecular structures within the cells in various tissues. These are large total doses delivered in small daily amounts over a period of time. Severe acute respiratory syndrome (SARS) is a life-threatening disease caused by a novel coronavirus termed SARS-CoV. The Importance of Dosimetry to the Medical Management of Persons Exposed to High Levels of Radiation. ARS, also known as radiation sickness, is caused by exposure to a high dose of penetrating, ionizing radiation over a short period of time. Nephrotic syndrome is the combination of nephrotic-range proteinuria with a low serum albumin level and edema. Common predisposing clinical conditions include sepsis, pneumonia, severe traumatic injury, and aspiration of gastric contents. However, all of these symptoms usually disappear in a day or two, and a symptom-free, latent period follows, varying in length depending upon the size of the radiation dose. Prasad KN. Acute radiation syndrome (ARS) is the primary threat to life after exposure to major doses of radiation.31 The diagnosis of ARS is based on a history of exposure and clinical findings (Box 105-1). Some people recover from radiation exposure, while others may die in weeks or months. Most of the other people who have died from it were … Bethesda , Maryland : Armed Forces Radiobiology Research Institute (AFRRI); 1999.
