Physical Effects of Nuclear Radiation

Nuclear energy is the energy emitted from the nucleus of an atom. This happens when the atom's mass turns into energy and the resulting rays are nuclear radiation. The physical effects of nuclear radiation on humans are dependent on several factors: type of radiation and rays, length of exposure and strength of the exposure.

Initial Radiation Exposure

• The physical effects associated with exposure to initial nuclear radiation, which is the emission that results from exposure the first time (about six to 12 hours), can cause headaches, nausea and vomiting in some cases. This exposure is usually not fatal.

Continued Radiation Exposure

• Depending on the strength of radiation and the duration of exposure, the physical effects of nuclear radiation can be as mild as initial radiation or can get gradually worse. Some effects include fatigue, ulcers, burns, bleeding, anorexia and cancer. Ultimately, death could result from continued radiation exposure.

Ray Effects Exposure

• Exposure to the various ray effects associated with nuclear radiation can cause various physical effects. Alpha rays cause no serious damage to your body when you are exposed to them. Beta rays are only slightly hazardous but can cause skin irritation, burns and eye damage. Gamma rays are very dangerous; contact with these rays can result in severe burns and tissue damage.

Inhaling or Ingesting

• Being close enough to nuclear radiation exposure means that you have the chance to inhale or ingest some nuclear particles. This can cause mild to severe damage to your body's cells and organs, depending on the amount and strength of the radiation. This can be fatal.

Radiation Strength

• Radiation is measured in roentgens. The higher number of roentgens, the greater risks to the human body. A low amount of roentgens will cause a mild reaction such as headaches and nausea, while a higher count will result in cancer and death.
