What is typically a sign of radiation sickness?

Nausea is a well-known symptom of radiation sickness and typically occurs in individuals exposed to high levels of radiation. This symptom arises as a result of damage to cells and tissues caused by ionizing radiation. The gastrointestinal system is particularly sensitive to radiation, and nausea can be an early indicator of exposure.

In addition to nausea, individuals with radiation sickness may experience other symptoms such as vomiting, diarrhea, fatigue, and various blood abnormalities. The onset of nausea generally indicates the body’s response to the physiological effects caused by radiation exposure and can manifest within hours to a few days following significant exposure. Recognizing nausea, along with other symptoms, is crucial for early diagnosis and treatment of radiation sickness to mitigate further health impacts.
