Unformatted text preview: Unit 1 Fundamental Concepts 1-13 Any organism will die if it is exposed to too much radiation. For some people, exposures above .05 C/Kg (200 R) to the whole body may be lethal. At .09 C/Kg (350 R), perhaps 5 percent of the exposed group would die within a month without medical attention. At .12 C/Kg (450 R), as stated earlier, half of the exposed group would probably die without medical attention. At .17 C/Kg (650 R), most would die without intense medical care. Hair loss results from the destruction of hair follicles in the skin. Hair loss may be temporary or permanent depending on the dose. Skin irritation is another effect likely to occur from acute exposures to radiation. A tingling sensation of the skin and some reddening may persist for a couple of days after exposure. This response is typical of a sunburn and the dead skin cells are obvious from the peeling of skin after the burn. But unlike sunburn, the irritation will return after some time has passed and persist for about 3 weeks. More severe skin burnsthe irritation will return after some time has passed and persist for about 3 weeks....
