Radiation illness is the result of a substantial dosage of radiation being given to your body over a short time (acute). The absorbed dose, or the amount of radiation taken into the body, influences how unwell you will become.

Radiation poisoning or acute radiation syndrome are other names for radiation illness. Common imaging techniques that employ low-dose radiation, such as X-rays and CT scans, do not induce radiation sickness.

Moreover, radiation illness is dangerous and often lethal, but it is uncommon. Most cases have taken place after nuclear industrial occurrences, such as the 1986 explosion and fire that affected the nuclear power plant at Chornobyl, Ukraine, since the atomic bombings of Hiroshima and Nagasaki, Japan, during World War II.


The intensity of radiation illness symptoms is determined by the amount of radiation you’ve consumed. The intensity of the radiated energy, the length of your encounters, and the distance between you and the origin of radiation all influence how much you absorb.

The type of exposure — complete or partial body — impacts the clinical symptoms. Radiation illness is also affected by how sensitive the damaged tissue is. The gastrointestinal tract and bone marrow, for example, are extremely vulnerable to radiation.

Possible signs may include:

  • Diarrhea
  • Vomiting and nausea
  • Fever
  • Headache
  • Hair loss
  • Disorientation or dizziness
  • Infections
  • Low blood pressure
  • Internal bleeding


Medical personnel employs a number of measures to estimate the absorbed radiation dosage when a person has been exposed to a high dose of radiation as a result of an accident or attack. This information is crucial for identifying the severity of the condition, the best treatments, and whether or not a person will recover.

The following information is crucial for establishing an absorbed dose:

  • Blood tests
  • Survey meter
  • Known exposure
  • Dosimeter
  • Vomiting and other symptoms
  • Type of radiation


Radiation sickness treatment goals include preventing future radioactive exposure, treating life-threatening injuries including trauma and burns, reducing symptoms, and managing pain.

  • Decontamination
  • Treatment for damaged bone marrow
  • Treatment for internal contamination
  • Supportive treatment

Additional medications or therapies may be given to you if you have radiation illness to treat:

  • Headache
  • Bacterial infections
  • Burns
  • Vomiting and nausea
  • Ulcers or sores
  • Dehydration
  • Diarrhea
  • Fever
