BodyWhen unstable nuclei of atoms will decay thus releasing particles, radiation will form and if such particles will be in contact with various organic materials for instance tissue, damage is almost contiguous, causing burns, cancer and maybe death.
Rem is the unit used to measure the radiation dosage and this will determine the amount of danger a person will be in after exposure. The Nagasaki and Hiroshima incidents were extremely fatal because of the high dosage of rems that was within the explosions, after this within the surroundings and in some areas from radioactive particles that were carried out to the upper atmosphere by the nuclear explosion and then that fell back to the earth’s surface, the fallout.
What about of rem dosage will endanger human life?
Studies have shown that a mere 25 rems may cause some alteration within the human body leading to a maximum of 100 rems that will not present any danger for human life and will not have any immediate harmful effects. What is registered above 100 rems may cause the first symptoms of radiation sickness that may include headaches, nausea, vomiting and a loss of white blood cells and doses over 300 rems will cause significant internal harm including damage to the cells that will line the digestive tract and to the nerve cells. The reaction to the loss of the white blood cells will make any radiation victim more exposed to diseases because they are the main defense of the body against any infection. Exposure to 450 rems or more is always fatal.
At the same time there is a risk of reducing the production of the blood pallets which in effect will aid blood clotting thus making victims vulnerable to hemorrhaging. Symptoms as fever and diarrhea may occur in many cases and because there is no effective treatment, death will occur within three days up to a maximum of two weeks depending solely on the amount of exposure.
For the survivors of radiation exposure there are complications as well leading them up to diseases such as lung cancer, leukemia (cancer of the blood), thyroid cancer, breast cancer and cancers of other organs.
Sadly, there is no effective medical treatment available for the potentially fatal doses and medical staff will have no tools to determine in time the amount of dosage that the human body was exposed and in spite of all efforts death will occur in most cases with extreme exposure. For the ones that received less radiation treatments may include bone-marrow transplants, which will renew the supply of white blood cells that were affected by the radiation, and blood transfusions.
