Radiation

The effects of radiation on the human body

What is Radiation

Radiation takes place when atoms decays and starts releasing ionizing particles, known as ionizing radiation. When these particles come into contact with organic material, such as human bones, they will damage them if levels are high enough, causing burns and cancer. Ionizing radiation can be fatal for humans.


The Effects of Radiation

Radiation can cause loss of appetite, fatigue, fever, nausea, vomiting, diarrhea, and possibly even seizures and coma. This stage of serious illness may last from a few hours to several months.


The information below indicates how radiation can affect the different parts of the human body.





1) Hair

The losing of hair quickly and in clumps occurs with radiation exposure at 200 rems or higher.



(2) Brain

Since brain cells do not reproduce, they won't be damaged directly unless the exposure is 5,000 rems or greater. Like the heart, radiation kills nerve cells and small blood vessels, and can cause seizures and immediate death.



(3) Thyroid

The certain body parts are more specifically affected by exposure to different types of radiation sources. The thyroid gland is susceptible to radioactive iodine. In sufficient amounts, radioactive iodine can destroy all or part of the thyroid. By taking potassium iodide, one can reduce the effects of exposure.



(4) Blood System

When a person is exposed to around 100 rems, the blood's lymphocyte cell count will be reduced, leaving the victim more susceptible to infection. This is often refered to as mild radiation sickness. Early symptoms of radiation sickness mimic those of flu and may go unnoticed unless a blood count is done.According to data from Hiroshima and Nagaski, show that symptoms may persist for up to 10 years and may also have an increased long-term risk for leukemia and lymphoma.



(5) Heart

Intense exposure to radioactive material at 1,000 to 5,000 rems would do immediate damage to small blood vessels and probably cause heart failure and death directly.



(6) Gastrointestinal Tract

Radiation damage to the intestinal tract lining will cause nausea, bloody vomiting and diarrhea. This is occurs when the victim's exposure is 200 rems or more. The radiation will begin to destroy the cells in the body that divide rapidly. These including blood, GI tract, reproductive and hair cells, and harms their DNA and RNA of surviving cells.



(7) Reproductive Tract

Because reproductive tract cells divide rapidly, these areas of the body can be damaged at rem levels as low as 200. Long-term, some radiation sickness victims will become sterile.




Outcome of Radiation Effects in Hiroshima

To further elaborate on the effects of radiation I have gathered some images and videos on the aftermath of the Hiroshima bombing.
