The development of Acute Radiation Syndrome (ARS) is a critical consideration for individuals exposed to a large dose of radiation, typically over a short period of time. ARS occurs due to significant damage to the body’s cells and tissues, which is particularly pronounced in rapidly dividing cells such as those found in bone marrow, gastrointestinal tract, and the skin.

The symptoms of ARS can manifest within hours after exposure, depending on the dose received, and may include nausea, vomiting, fatigue, and decreased blood cell counts leading to a greater risk of infection and bleeding. The severity of ARS is dependent on the dose and type of radiation encountered, making it a direct and serious consequence of high-dose radiation exposure.

While chronic fatigue syndrome, general malaise, and respiratory distress can be associated with various health conditions, they do not directly result from exposure to high levels of radiation in the way that ARS does.
