Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
Exposure to too much of this radiation in a short time can damage the body's cells and its ability to fix itself, which is a condition called acute radiation sickness.
If a group of people is exposed to a 50 to 59 rems acute (within 24 hours) radiation dose, none will get radiation sickness. If the group is exposed to 60 to 180 rems, 50% will become sick with radiation poisoning. If medically treated, all of the 60–180 rems group will survive.
The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns.
Nplate, manufactured by U.S. drugmaker Amgen, was approved by the Food and Drug Administration in 2021 to treat injuries caused by acute radiation syndrome, also known as radiation sickness.
When dried and frozen, Deinococcus radiodurans could survive 140,000 grays, or units of X-and gamma-ray radiation, which is 28,000 times greater than the amount of radiation that could kill a person.
Infections caused by exposure to ionizing radiation can be extremely dangerous, and are of public and government concern. [ 1 ] [ 2 ] Numerous studies have demonstrated that the susceptibility of organisms to systemic infection increased following exposure to ionizing radiation. [ 1 ]
