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). If you are a patient, we strongly advise that you consult with your physician to interpret the information provided as it may apply to you.
