Latent stage: In this stage, the patient looks and feels generally healthy for a few hours or even up to a few weeks.The symptoms may last (episodically) for minutes up to several days. Prodromal stage (N-V-D stage): The classic symptoms for this stage are nausea, vomiting, as well as anorexia and possibly diarrhea (depending on dose), which occur from minutes to days following exposure.Death likely is due to collapse of the circulatory system as well as increased pressure in the confining cranial vault as the result of increased fluid content caused by edema, vasculitis, and meningitis.

Cardiovascular (CV)/ Central Nervous System (CNS) syndrome: the full syndrome will usually occur with a dose greater than approximately 50 Gy (5000 rads) although some symptoms may occur as low as 20 Gy or 2000 rads.Destructive and irreparable changes in the GI tract and bone marrow usually cause infection, dehydration, and electrolyte imbalance. Survival is extremely unlikely with this syndrome.Gastrointestinal (GI) syndrome: the full syndrome will usually occur with a dose greater than approximately 10 Gy (1000 rads) although some symptoms may occur as low as 6 Gy or 600 rads.The primary cause of death is the destruction of the bone marrow, resulting in infection and hemorrhage. The survival rate of patients with this syndrome decreases with increasing dose.Bone marrow syndrome (sometimes referred to as hematopoietic syndrome) the full syndrome will usually occur with a dose between 0.7 and 10 Gy (70 – 1000 rads) though mild symptoms may occur as low as 0.3 Gy or 30 rads 4.Fractionated doses are less effective at inducing ARS than a single dose of the same magnitude. These are large total doses delivered in small daily amounts over a period of time. Fractionated doses are often used in radiation therapy.The dose must have been delivered in a short time (usually a matter of minutes).Most radiation injuries are local, frequently involving the hands, and these local injuries seldom cause classical signs of ARS.The entire body (or a significant portion of it) must have received the dose 3.

High energy X-rays, gamma rays, and neutrons are penetrating radiations.

The radiation must be penetrating (i.e., able to reach the internal organs).

Radioactive materials deposited inside the body have produced some ARS effects only in extremely rare cases.

The dose usually must be external ( i.e., the source of radiation is outside of the patient’s body).

Mild symptoms may be observed with doses as low as 0.3 Gy or 30 rads.

The radiation dose must be large (i.e., greater than 0.7 Gray (Gy) 1, 2 or 70 rads).

The required conditions for Acute Radiation Syndrome (ARS) are: Examples of people who suffered from ARS are the survivors of the Hiroshima and Nagasaki atomic bombs, the firefighters that first responded after the Chernobyl Nuclear Power Plant event in 1986, and some unintentional exposures to sterilization irradiators. The major cause of this syndrome is depletion of immature parenchymal stem cells in specific tissues. Information on Acute Radiation Syndrome (ARS) for members of the public can be found at Īcute 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).
