Acute radiation syndrome ars. View cdc fact sheet. Acute radiation syndrome is rare and comes from extreme events like a nuclear explosion or accidental handling or rupture of a highly radioactive source.
This level of radiation would be like getting the radiation from 18 000 chest x rays distributed over your entire body in this short period. Depending on the dose the effects of radiation can be mild or life threatening. Nuclear accidents the work environment and some medical treatment can all be sources of radiation poisoning.
When humans are exposed to this radiation there is a risk that it causes chemical changes in cells which can kill or makes cells abnormal. When radioactive chemicals break down they release a certain amount of radiation. Nuclear fallout poses health dangers particularly in the form of cancer to humans in the form of radiation.
The amount of radioactive material being released from the damaged nuclear reactors in japan and the eventual impact it will have on human health are still being determined. It is emitted by sun the radioactive material in earth outer space food rocks and even the human body. It comes from both natural and manmade sources.
Radiation exists in the environment as a normal component of nature. Read this article to learn about the effects of radiation on human body. Several factors are involved in determining the potential health effects of exposure to radiation.
Certain body parts are more specifically affected by exposure to different types of radiation sources. Radiation effects on humans. Effects of nuclear weapons.
The killing of cells in affected tissues for example may be detectable within minutes after exposure whereas degenerative changes such as scarring.
Effect of nuclear radiation on human body. The effects of nuclear radiation on different areas of a human body. Those who are exposed to 200 rems or more of radiation may have nuclear radiation effects such as the loss of hair or hair that clumps together. There are times when the brain can be damaged but this happens only at an exposure that is higher than 5000 rems exposure this high may cause damage to the nerves and blood vessels. The effects of radiation on the human body radioactive materials are hazardous.
Nuclear radiation can ionise chemicals within a body which changes the way the cells behave. In a nuclear explosion the human body can be irradiated by at least three processes. The first and most major cause of burns is due to thermal radiation and not caused by ionizing radiation. Thermal burns from infrared heat radiation these would be the most common burn type experienced by personnel.
If people come in direct contact with fallout beta burns from shallow ionizing beta. Radiation radiation effects on organs of the body somatic effects. A wide variety of reactions occur in response to irradiation in the different organs and tissues of the body. Some of the reactions occur quickly while others occur slowly.
