What is the correct order of phases acute radiation syndrome?

Acute radiation syndrome is a condition caused by exposure to a high amount of radiation over a short period of time. It can be life-threatening, and the symptoms vary depending on the dose of radiation received. The phases of acute radiation syndrome are:

1. Prodromal phase: This phase occurs within the first few hours after exposure to radiation. Symptoms include nausea, vomiting, headache, fatigue, and diarrhea.

2. Latent phase: This phase lasts from a few days to several weeks. During this phase, the symptoms of the prodromal phase disappear and the person may feel better. However, the body is still being damaged by the radiation.

3. Manifest illness phase: This phase begins when the symptoms of the prodromal phase return and become more severe. It is also known as the critical phase of acute radiation syndrome, as it is during this phase that the most serious complications occur. Symptoms can include fever, chills, bleeding, organ failure, and hair loss.

4. Convalescent phase: This phase begins when the symptoms of the manifest illness phase start to improve. It can last for several months to years, and during this time the person may gradually recover their health. However, they may still have some long-term effects from the radiation exposure.
