Radiation Reaction

Radiation reaction: pathological changes caused by ionizing radiation

A radiation reaction is a set of pathological changes that occur in the human or animal body immediately during or shortly after exposure to ionizing radiation. These changes are usually reversible and may be associated with various diseases.

Ionizing radiation includes gamma rays, x-rays, and high-energy particles such as beta particles and alpha particles. This radiation can be natural, such as radiation from radon, or man-made, such as medical X-rays or radiation therapy.

A radiation reaction can manifest itself at different levels of the body, ranging from changes at the cellular level to changes in organs and systems. For example, a radiation reaction can cause changes in DNA, leading to mutations and disruption of cell functioning. This can lead to various diseases such as cancer, leukemia and others.

In addition, the radiation reaction can cause changes in the circulatory system, which can lead to anemia and other circulatory diseases. It can also cause changes in the immune system, which increases the risk of developing infections.

However, not all people are at the same risk of radiation reactions. The risk depends on the dose of radiation, duration of exposure and sensitivity of the body. Some people may be more sensitive to radiation reactions, such as children and pregnant women.

A wide range of measures are used to protect against radiation reactions, including radiation protection in the workplace, the use of protective equipment for medical personnel and patients, and control of radiation dose during radiation therapy.

In conclusion, radiation reaction is a serious disease caused by ionizing radiation. However, taking precautions and controlling the radiation dose can help reduce the risk of developing this disease.

**Radiation reaction:** a set of pathological changes (disease) that occur directly in response to radiation (often radioactive - radiation) and manifest themselves in the form of dysfunction of organs. They occur in tissues and organs that have been exposed to radiation, as well as in affected areas of the body where there was no primary radiation damage. All changes that occur during radiation exposure are divided into three main categories: damage to the main function of the organ (gamia), damage to the functions of the organ (bimia) and nonspecific disorders.
