The nuclear effects on Humans

The medical furnishings of a nuclear bang aloft bodies can be put into four categories:

Initial date -- the aboriginal 1–2 weeks, in which are the greatest cardinal of deaths, with 90% due to 2. 2.
thermal abrasion and/or bang furnishings and 10% due to super-lethal radiation exposure
Intermediate date -- from 3–8 weeks. The deaths in this aeon are from ionization radiation in the average baleful range
Late aeon -- abiding from 8–20 weeks. This aeon has some advance in survivors' condition.
Delayed aeon -- from 20+ weeks. Characterized by “numerous complications, mostly accompanying to healing of thermal and automated injuries accompanying with infertility, sub-fertility and claret disorders acquired by radiation.” Also, ionizing radiation from fallout can account abiogenetic effects, bearing defects, cancer, amaurosis and added furnishings in organs and tissue.

In a nuclear explosion the human body can be irradiated by at least three processes. The first (the major cause of burns) is not caused by ionizing radiation.

Thermal burns from infrared heat radiation.
Beta burns from shallow ionizing beta radiation (this would be from fallout particles; the largest particles in local fallout would be likely to have very high radioactivity because they would be deposited so soon after detonation; it is likely that one such particle upon the skin would be able to cause a localized burn). However, these decay particles are very weakly penetrating and have a short range.
Gamma burns from highly penetrating gamma radiation. This would likely cause deep gamma penetration within the body, which would result in uniform whole body irradiation rather than only a surface burn. In cases of whole body gamma irradiation (circa 10 Gy) due to accidents involving medical product irradiators, some of the human subjects have developed injuries to their skin between the time of irradiation and death.

In the picture on the right, the normal clothing that the woman was wearing would have been unable to attenuate the gamma radiation and it is likely that any such effect was evenly applied to her entire body. Beta burns would be likely all over the body due to contact with fallout, but thermal burns are often on one side of the body as heat radiation does not penetrate the human body. In addition, the pattern on her clothing has been burnt into the skin. This is because white fabric reflects more infra-red light than dark fabric. As a result, the skin underneath dark fabric is burned more than the skin covered by white clothing.

There is also the risk of internal radiation poisoning by ingestion of fallout particles.
