How the effects of Nuclear Radiation Hazards

a. What happens if we are exposed to high levels of radiation? Exposure to radiation can cause poisoning that caused significant damage to human tissue can include premature aging and even death. Low-level radiation exposure in the long term could also exacerbate health. Reportedly, several workers at one of the reactor showed symptoms of illness due to radiation during a disaster.
b. What are the symptoms of radiation poisoning? Nausea, vomiting, and diarrhea are usually the initial symptoms and appear in a minute or a few days after exposure to radiation. In fact, if someone has an acute radiation syndrome and the symptoms appeared only a few minutes, they still may look fine, but only temporarily.
Additional symptoms will eventually follow, including loss of appetite, fatigue, fever, and possibly convulsions and coma. This phase may last several hours or several months. Radiation poisoning is also commonly cause skin damage.
c. How dangerous levels of radiation? Radiation is measured in Sieverts scale and effects of radiation poisoning also depends on the number of Sieverts. For example, 1 Sievert of radiation can cause bleeding and 2,000 Sieverts can cause loss of consciousness within minutes and death within hours.
d. Does radiation poisoning can be treated? Yes, but only in some cases. Potassium iodide can block radioactive iodine when taken to the thyroid gland, protecting it from injury. However, it will not protect other parts of the body, or otherwise damage the thyroid
