What Happens With Localized Exposure
When a small section of the skin is subject to a blast of something like 15 to 20 gray, the skin will act in a disconcerting way. First off, you’ll experience something like a burn—swelling, redness, and itchiness will ensue. After about a week or so, the affected region will lose all of its hair. At about the third week, the exposed area will begin to experience skin sloughing (i.e., peeling). When you experience something like 50 grays, the affected area will suffer far more quickly. You will, in other words, experience burning right away. And from there, blistering will occur.
What Acute Radiation Syndrome Is
Acute radiation syndrome is what you will get when you have a full body exposure to 2 grays of radiation. When you suffer through this, you will experience four waves: prodrome, latent, illness, and recovery. The extent of each phase is only determined by the amount of radiation exposure you received. It is interesting to hear that it only takes 3.5 grays if you want to kill half the population through full body radiation. However, acute exposure of a much higher caliber is not quite as disconcerting as you would think. Acute exposure might not bring about organ failure and an assortment of ailments that lead to death when it comes to radiation sickness.
