2020年3月20日 · High Radiation Doses Because radiation from nuclear material is strictly regulated, humans seldom experience large doses (~50 rem) of radiation. Nonetheless, lower doses can still damage or alter the genetic code (DNA) of irradiated cells.

2024年2月13日 · Radiation sickness happens when high-energy radiation damages or destroys certain cells in the body. Areas of the body most at risk of being affected by high-energy radiation are the bone marrow cells and the lining of the intestinal tract.

2024年2月19日 · High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.

Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] .

At very high doses, radiation can impair the functioning of tissues and organs and produce acute effects such as nausea and vomiting, skin redness, hair loss, acute radiation syndrome, local radiation injuries (also known as radiation burns), or even death.

2023年5月26日 · Radiation poisoning happens after exposure to very high doses of radiation. Learn about the causes, how it affects the body, and what to do in an emergency.

2024年10月2日 · Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects …

2025年1月31日 · If you experience any symptoms of Acute Radiation Syndrome or Cutaneous Radiation Injury (CRI) after a radiation emergency, seek medical attention as soon as it is safe.

2023年7月27日 · Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation.

2024年3月11日 · High doses of radiation can cause massive damage to organs of the body and kill the person. The exposed person loses white blood cells and the ability to fight infections. Diarrhea and vomiting are likely. Medical treatment can help, but the condition may still be fatal in spite of treatment.
