A complete and SCIENTIFIC explanation on hair loss & and skin melting caused by atomic radiation please?

Hello can someone give a complete and SCIENTIFIC explanation on hair loss and skin melting caused by radiation after an atomic explosion? I can only find general and brief explanations on the internet. Thank you.A complete and SCIENTIFIC explanation on hair loss %26amp; and skin melting caused by atomic radiation please?
Firstly the two symptoms are not really related. When a nuclear explosion causes the skin to melt from the heat, the victim is fairly close to Ground Zero, though not so close as the be vaporized by the blast. Such a victim would not need to be treated as they would not survive the damage. They would be a corpse. The melting from heat needs no explanation, but to actually melt rather than be cooked or incinerated would be rare, there would only be a small range where that might occur (perhaps behind glass as infrared radiation is not stopped by glass). I think that you more likely mean second degree burns rather than turning skin into a liquid (third degree is charring).





The Hair loss that you mention, I take it, is not from burning in the explosion when the victim would normally be dead or singed at a distance with clothes on fire and maybe blind. Hair loss occurs in those survivors from an explosion who have been exposed to radiation of sufficient dose to make them very sick or in the end kill them. Those who get their radiation from the actual blast have usually also been so close as to be vaporized or killed outright. Victims with radiation poisoning are more likely to have been irradiated from the fallout cloud which settles down on the land say half an hour after the blast, depending on the prevailing winds and height of the detonation. Ground detonating blasts raise the most dust and distribute the most fallout. Radiation is like piercing an apple thousands of times with a fine needle, the apple shows no signs at first but later goes brown and is seen as decaying. The gamma rays drill through the body's tissues, penetrating the cells causing damage, smashing into the cellular molecules that will only work if they are intact. The same effect can be observed in radiation therapy on cancer patients with leukemia. Where the radiation dose is not light but yet not high enough to immediately kill, the most susceptible tissues in the body show the signs of dying first. These are the short lived cells that have a high reproduction rate. With their process no longer functioning they fail to replicate themselves before they die. These cells are, for instance, those of the bloods red cells, stomach, intestines and mouth where there is a high replacement rate due to factors like wear and tear or digestive acids. Ulcers and hemorrhage in these areas are common first signs of radiation poisoning. Then, as the hair follicles in the skin are imbedded in dying or dead cells, the hair roots are no longer anchored well and the hair falls out or can be easily pulled out. The hair itself is dead tissue so no change to it might be observable. The immune system is down and such patients can easily die of ordinary infections. Severe cases would need a bone marrow transplant as part of their treatment, and a lot of luck. Milder cases may recover and live on.
