Prolly scare the sh1t out of em if I start going through LD500, LD 250 etc anyway
They can get it all much better worded from Wikipedia
http://en.wikipedia.org/wiki/Median_lethal_dose
Lets give em something to worry about
The four stages of ARS are:
•Prodromal stage (N-V-D stage): The classic symptoms for this stage are nausea, vomiting, as well as anorexia and possibly diarrhea (depending on dose), which occur from minutes to days following exposure. The symptoms may last (episodically) for minutes up to several days.
•Latent stage: In this stage, the patient looks and feels generally healthy for a few hours or even up to a few weeks.
•Manifest illness stage: In this stage the symptoms depend on the specific syndrome (see Table 1) and last from hours up to several months.
•Recovery or death: Most patients who do not recover will die within several months of exposure. The recovery process lasts from several weeks up to two years.
These stages are described in further detail in Table 1

Recovery
Hematopoietic
(Bone Marrow)
> 0.7 Gy (> 70 rads)
(mild symptoms may occur as low as 0.3 Gy or 30 rads)
• Symptoms are anorexia, nausea and vomiting.
• Onset occurs 1 hour to 2 days after exposure.
• Stage lasts for minutes to days.
• Stem cells in bone marrow are dying, although patient may appear and feel well.
• Stage lasts 1 to 6 weeks.
• Symptoms are anorexia, fever, and malaise.
• Drop in all blood cell counts occurs for several weeks.
• Primary cause of death is infection and hemorrhage.
• Survival decreases with increasing dose.
• Most deaths occur within a few months after exposure.
• in most cases, bone marrow cells will begin to repopulate the marrow.
• There should be full recovery for a large percentage of individuals from a few weeks up to two years after exposure.
• death may occur in some individuals at 1.2 Gy (120 rads).
• the LD50/60†is about 2.5 to 5 Gy (250 to 500 rads)
Gastrointestinal (GI)
> 10 Gy (> 1000 rads)
(some symptoms may occur as low as 6 Gy or 600 rads)
• Symptoms are anorexia, severe nausea, vomiting, cramps, and diarrhea.
• Onset occurs within a few hours after exposure.
• Stage lasts about 2 days.
• Stem cells in bone marrow and cells lining GI tract are dying, although patient may appear and feel well.
• Stage lasts less than 1 week.
• Symptoms are malaise, anorexia, severe diarrhea, fever, dehydration, and electrolyte imbalance.
• Death is due to infection, dehydration, and electrolyte imbalance.
• Death occurs within 2 weeks of exposure.
• the LD100‡ is about 10 Gy (1000 rads)
Cardiovascular (CV)/ Central Nervous System (CNS)
> 50 Gy (5000 rads)
(some symptoms may occur as low as 20 Gy or 2000 rads)
• Symptoms are extreme nervousness and confusion; severe nausea, vomiting, and watery diarrhea; loss of consciousness; and burning sensations of the skin.
• Onset occurs within minutes of exposure.
• Stage lasts for minutes to hours.
• Patient may return to partial functionality.
• Stage may last for hours but often is less.
• Symptoms are return of watery diarrhea, convulsions, and coma.
• Onset occurs 5 to 6 hours after exposure.
• Death occurs within 3 days of exposure.
• No recovery is expected.
* The absorbed doses quoted here are “gamma equivalent†values. Neutrons or protons generally produce the same effects as gamma, beta, or X-rays but at lower doses. If the patient has been exposed to neutrons or protons, consult radiation experts on how to interpret the dose.
†The LD50/60 is the dose necessary to kill 50% of the exposed population in 60 days.
‡ The LD100 is the dose necessary to kill 100% of the exposed population
