Acute Radiation Syndrome (ARS), also known as radiation sickness or radiation poisoning, is a rare but severe illness caused by exposure to high levels of ionizing radiation. It is most commonly associated with nuclear accidents or warfare, although it can also occur from other sources of radiation exposure such as medical radiation treatments or industrial accidents.
The severity of ARS is determined by the amount of radiation exposure and the duration of exposure. Symptoms can vary depending on the dose of radiation, but typically include nausea, vomiting, diarrhea, and fever. In severe cases, ARS can also cause burns, internal organ damage, and even death.
There is no cure for ARS, but treatment options may include medications to manage symptoms, such as anti-nausea drugs and antibiotics to prevent infections. Patients may also require blood transfusions or bone marrow transplants to replace damaged cells.
Prevention and protection from ARS includes avoiding exposure to sources of radiation whenever possible, using proper protective measures (such as lead shields or protective clothing), and following safety guidelines in environments where radiation is present.
