Effects of Radiation on the Human Body
The human body does not handle extreme ammounts of radiation verry well. You can be exposed to radiation in verious amounts. Everyone is exposed to radiation in some way every day. Eather in the form of sun light, or even nuclear radiation. Prolonged exposer to any type of radiation has some effect on the human body. In the form of light radiation your skin most commenly will just get burned, or worse you can get skin cancer. But if you are exposed to nuclear radiation the effects are more worse. First your hair will start to fall out in patches. this is because the cells in your skin repoduce more quickley than others. And just like in cancer treatment the cells die. 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. 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. 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. Overall radiation is not good for the human body. In very small ammounts you can live, but if you are exposed to great ammounts you will most likley die.

I never knew what radiation actually did to someone, though i knew it was harmful. One related form of radiation is whatever is used during chemo, even though chemo is helpful to us in small amounts. Since chemo is a form of radiation it does cause some of the effects of radiation sickness, such as loss of hair and mild flu-like symptoms. And people always worry about radiation from microwaves and stuff, but the radiation probably not enough to cause any damage in your body.
ReplyDeleteVery informative and enlightening! keep it up
Graham, first off, really cool report. Second, I'm really suprised how radiation really does kill you slowly. The only time that I ever worry about radiation is when I'm playing Fallout 3. Whenever I got radiation sickness I never really made the connection that it really messed up your body (Explosive dirreha, muscle spasms. etc) Really interesting article Graham
ReplyDeletehey Graham, i never thought that radiation was that harmful. i wounder how much rems of radiation a x-ray would give you. I also found it was interesting that victims Hiroshima and Nagasaki, could show symptoms for ten years.
