Acute Radiation Syndrome (ARS)
a serious illness caused by receiving a dose greater than 75 rads of penetrating radiation to the body in a short time (usually minutes). The earliest symptoms are nausea, fatigue, vomiting, and diarrhea. Hair loss, bleeding, swelling of the mouth and throat, and general loss of energy may follow. If the exposure has been approximately 1,000 rads or more, death may occur within 2 – 4 weeks. For more information, see CDC’s fact sheet “Acute Radiation Syndrome” at emergency.cdc.gov/radiation/ars.asp.

Radiation poisoning
Radiation poisoning, also called "radiation sickness", 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. Many of the symptoms of radiation poisoning occur as ionizing radiation interferes with cell division. This interference allows for treatment of cancer cells; such cells are among the fastest-dividing in the body, and may be destroyed by a radiation dose that adjacent normal cells are likely to survive.
