	Radiation sickness
		Radiation sickness is illness and symptoms resulting from excessive exposure to radiation.
		Radiation sickness is generally associated with acute exposure and has a characteristic set of symptoms that appear in an orderly fashion.
		Because it is difficult to determine the amount of radiation exposure from accidents, the best indications of the severity of the exposure are: the length of time between the exposure and the onset of symptoms, the severity of symptoms, and severity of changes in white blood cells.

	radiation sickness - Encyclopedia.com
		The biological action of radiation is not fully understood, but it is believed that a disturbance in cellular activity results from the chemical changes caused by ionization (see ion).
		Radiation sickness may occur from exposure to a single massive emanation such as a nuclear explosion (such as Hiroshima and Nagasaki), or it may occur after repeated large exposure or to even very small doses in a plant or laboratory, since radiation effects are cumulative.
		Radiation sickness may be fairly mild and transitory, consisting of weakness, loss of appetite, vomiting, and diarrhea.

		Radiation can also cause little understood changes to the body's genes, which can be manifested through the development of diseases such as cancer later in life, and possibly as birth defects in future generations.
		Radiation causes atoms, the basic building block of the body's cells, to become electrically charged which can be potentially dangerous.
		Radiation penetrates the body and is wholly or partially absorbed by soft and hard tissue.

	Radiation Sickness or Death Caused by Surreptitious Administration of Ionizing Radiation to an Individual Report No. 4 ...
		The present study and analyses of radiation sickness or death caused by surreptitious administration of ionizing radiation to an individual is presented to BMIS in response to the request of the Office of the Assistant Chief of Staff for Intelligence, Department of the Army to S.I.C. dated 11 March 1969.
		Of greatest importance in the diagnosis of radiation damage is the suspicion that it might have occurred (i.e., its inclusion in the differential diagnosis), the availability of adequate hospital and laboratory facilities and the availability of expert consultation.
		The lack of precise predictability of response to a radiation dose results from the paucity of data on man and the fact that most of the existing data is derived from radiation accidents in which the actual dose received by the patient and its distribution over his body is difficult to determine with accuracy.

	Radiation sickness - CNN.com
		Radiation sickness is illness that occurs from exposure to a large amount of radiation.
		The way in which you receive radiation — by breathing in radioactive material, by ingesting it with food or water, or by being exposed to intense beams of radiation — also has an effect on the signs and symptoms of radiation sickness.
		Radiation experts from the Centers for Disease Control and Prevention believe that most dirty bombs wouldn't be able to release levels of radiation high enough to cause immediate serious illness, except for people in very close proximity to the explosion.

	ImmuneRegen - treatment for radiation sickness (Site not responding. Last check: )
		Radiation sickness, known as acute radiation sickness or syndrome, is a serious illness that occurs when the entire body (or most of it) receives a high dose of radiation, usually over a short period of time.
		Radiation can affect the body in a number of ways, and the adverse health consequences of exposure may not be seen for many years.
		These effects can range from mild, such as skin reddening, to serious effects such as cancer and death, depending on the amount of radiation absorbed by the body (the dose), the type of radiation, the route of exposure, and the length of time a person is exposed.

	Questions and Answers.
		Radiation we are exposed to from our environment include Cosmic (high energy particles and EM from outside of our galaxy), Cosmic induced (C-14, Tritium made in the atmosphere by interactions with cosmic radiation), Solar (UV from the sun mostly, but in space can be particles), and terrestrial (Uranium, Thorium, Radon contained in the Earth itself).
		Radiation sickness is not generally well understood by the public, yet there term is commonly used, or I should say, mis-used in Hollywood films and the written media.
		This is what radiation sickness is. The some of the most sensitive cells in a human are the active cells in the lining of the intestine (called crypt cells), white blood cells, and the cells that make red and white blood cells.

	Clinical Course of Acute Radiation Sickness
		This is a nonspecific clinical response to acute radiation exposure.
		It is not diagnostic of the degree of radiation injury; however, in the absence of associated trauma and an early onset, it does suggest a large radiation exposure.
		Because of the extreme variability in duration of the latent phase, it is not practical to hospitalize all personnel suspected of having radiation injury early in the latent phase unless radiation injury has been diagnosed.

	Radiation Sickness - Information and Treatment
		Radiation sickness is the result of exposure to radiation, whether accidental, as in the case of a nuclear power plant accident, or intentional, as in the case of radiation therapy for cancer called chemotherapy.
		This is why radiation is used for cancer therapy, but it also has a very significant risk and danger to the bone marrow and mucous membranes, as well as other types of tissue.
		In the case of accidental exposure to radiation, contaminated clothing, gloves, and other materials should be removed immediately, and extremely thorough washing begun to remove as much of the contamination as possible.

	Ch. 13: Surviving Without Doctors - Nuclear War Survival Skills
		The first symptoms of radiation sickness are nausea, vomiting, headache, dizziness, and a general feeling of illness.6 These symptoms begin several hours after exposure to acute doses of 100 R to 200 R. and within 30 minutes or less after receiving a fatal dose.
		The large radiation doses that many survivors of a nuclear attack would receive would result in serious long-term risks of death from cancer, but the lifetime risks from even large wartime radiation doses are not as bad as many people believe.
		For external gamma-ray radiation from fallout, the numerical value of an exposure or dose given in roentgens is approximately the same as the numerical value given in rems or in rads.

	Radiation: Affects on Humans
		The Quality Factor of a given type of radiation is determined in the following way: A group of RBE measurements are made using a variety of cells and/or tissue (these experiments aren't cheap to perform and the number that are done is driven by the overall interest in the radiation being studied).
		Basically, the RBE is determined by comparing the damage of the radiation to the cells/tissue of interest to that with an equal dose of gammas or xrays.
		Given that only moderate doses of radiation are encountered (and thus acute effects are not seen) the long-term effects of radiation become the most important to consider.

	Is radiation sickness contagious? - By Daniel Engber - Slate Magazine
		The polonium isotope discovered in Litvinenko's body emits radiation only in the form of alpha particles, which are the charged nuclei of helium atoms.
		Unlike other forms of radiation, like gamma rays or X-rays, alpha emissions can be blocked by something as insubstantial as a piece of paper or the layer of dead cells on the surface of the skin.
		Doctors measure these effects in terms of "rems" or "sieverts," which are related to the type of radiation and the amount of energy that gets absorbed by a given mass of tissue.
