There are some things that should scare every single one of us... and radiation is towards the top of that list.
For those unfamiliar, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium, as defined by world-nuclear.com. When it comes to humans, high levels of exposure can be hazardous, but at low levels, it's believed to be a little less harmless.
Key word is "believed", because it can do some harm over time, naturally.
Thanks to the video below from Seeker's YouTube, we now have an idea at just how bad radiation on the human body can really be.
In addition to the information from the video above, outside research from the website AtomicArchive explains the risks a little bit more, with this being how radiation can impact certain part of your body.
The losing of hair quickly and in clumps occurs with radiation exposure at 200 rems or higher.
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.
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.
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.
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.
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.
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.
So, yeah, for all you people who enjoy heading to the tanning bed or live close to a nuclear power plant—we hope you don't—it might be time to freak out just a little bit.
