So I Watched CHERNOBYL… Now What? Revisiting Acute Radiation Syndrome
Military attacks or natural disasters affecting civilian nuclear power plants are extremely unlikely. However, physicians ought to be prepared to care for the more plausible patient injured from working in an industrial, military, research, or medical setting with known radiation risks. Alternatively, cases of radiation sickness have occurred as a result of patients unwittingly handling discarded radiation sources.
Pathophysiology of the Effects of Radiation
Radiation injury is caused by deposition of energy in tissues, which promotes free radicals and disruption of DNA and other cellular structures. Radiation exposure can occur through inhalation, ingestion,…

Drug Can Stop Radiation Poisoning Up To 24 Hours After Exposure
The existing treatment, a compound called Prussian blue, absorbs some of the radiation that causes damage in the body, but doesn’t protect the intestinal barrier specifically. This has inspired a search for drugs that can “mitigate the effects of radiation post exposure, accelerate tissue repair in radiation-exposed individuals, and prevent mortality,” the researchers write. The new drug, called TP508, was originally designed to help patients regenerate cells by increasing blood flow and decreasing inflammation, according to the press release—it’s been used to ensure that diabetic patients don’t lose a foot, or to help patients with wrist fractures heal more quickly.

Acute Radiation Syndrome
Acute Radiation Syndrome (ARS) (sometimes known as radiation toxicity or radiation sickness) is an acute illness caused by irradiation of the entire body (or most of the body) by a high dose of penetrating radiation in a very short period of time (usually a matter of minutes). The major cause of this syndrome is depletion of immature parenchymal stem cells in specific tissues.

Patients contaminated with radiation pose very little risk to health care providers when appropriate precautions and decontamination procedures are employed.
So I Watched CHERNOBYL… Now What? Revisiting Acute Radiation Syndrome
Although more than 119 million U.S. residents live within 50 miles of a nuclear power plant, most emergency physicians are unfamiliar with management of radiation-related injuries, including mass casualty from nuclear accidents.

Stanford University
Acute Radiation Syndrome (ARS) is an immediate illness that results from excessive radiation exposure over a short period of time. 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. Cellular damage from radiation happens within microseconds of exposure, and the onset of ARS varies from a few hours to weeks.
