This varies significantly depending on the dosage received and the individual's response to the poisoning. There are different scales for use in measuring the dosage. One commonly used measurement of the radiation absorbed dose of Roentgens in humans or other mammals is REMs (Roentgen Equivalent Man/Mammal). If you use these units in association with the Gray Scale, then 100 REMs = 1 GY on the Gray Scale.
Early symptoms of radiation poisoning include nausea and vomiting, diarrhea, headache, fever, and abnormal central nervous system (CNS) function. These will usually appear within hours of exposure of larger doses. Increasing doses increase the severity of these symptoms and shorten the timeframes of the progression of the symptoms to morbidity and mortality.
Exposure of humans to:
1-2 GY:
Results in a mild expression of the above symptoms and usually no deaths, but can dramatically increase the potential for long term effects, such as cancer or genetic damage, as do all the following exposures.
2-6 GY:
Results in slightly more severe early symptoms, and up to 50% mortality in seven to twenty-eight days.
6-8 GY:
Results in severe symptoms within 3 - 4 hours such as diarrhea, nausea and vomiting, very high fever, severe headache and 100% mortality in less than seven days.
8-30 GY:
Results in very severe symptoms in less than 10 minutes, rapid incapacitation and CNS involvement with 100% mortality within 2 hours of exposure.
30 GY and over:
Results in seizures and tremors and 100% mortality in under 30 minutes.

How long does it take for radiation sickness symptoms to appear?
If it is a major overexposure, a few days or a week perhaps. Small overdoses may take years to produce any effect, then it may be argued these are just effects of ageing or exposure to chemicals etc. Radiation sickness is therefore reserved for sickness arising due to known massive overdoses.
What is radioactive half-life used for?
Radioactive half-life is used to measure the rate at which a radioactive substance decays. It is important in determining the amount of time it takes for half of a radioactive substance to decay into a stable form. This information is useful in various fields such as medicine, environmental science, and geology for dating purposes and evaluating risks associated with radioactive materials.
If the half-life of a radioactive substance is 10 hours how long will it take for 50 percent of it to decay?
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.
When an atom undergoes radioactive decay when does it become a completely different element?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
What is the meaning of radioactive as a safety symbol?
The "radioactive" safety symbol warns you that radioactive material or a radiation producing machine is near the symbol and you should take precautions to ensure that you are not unnecessarily exposed to ionizing radiation.
How long does it typically take for kennel cough symptoms to appear in dogs?
Kennel cough symptoms in dogs typically appear within 2 to 14 days after exposure to the infectious agent.
How long does it take for hepatitis A symptoms to appear?
The time from exposure to HAV and the onset of symptoms ranges from two to seven weeks and averages about a month.
How long does it take to be diagonose with bipolar disorder?
usually at least 10 years after symptoms appear, if you are lucky.
Why does it take so long for the symptoms of salmonella food poisoning to appear?
within 8 to 72 hours
How long does it take rickettsialpox symptoms to appear?
After a person has been bitten by an infected mite, there is a delay of about 10 days to three weeks prior to the onset of symptoms.
How long does asbestosis take to develop?
Symptoms of the disease do not usually appear until 15-20 years after initial exposure to asbestos
How long does it take for HIV symptoms to start showing?
How long does it take for HIV symptoms to start showing
How long does CO poisoning take?
The symptoms of CO poisoning and the speed with which they appear depend on the concentration of CO in the air and the rate and efficiency with which a person breathes.
How soon do symptoms of malaria appear?
From the NHS website:"Symptoms of malaria usually appear 10-15 days after you are bitten. However, depending on the type of parasite you are infected with, it can take a year for symptoms to show."
How long after contamination of listeria bacteria do symptoms appear?
Symptoms of listeria infection can appear within a few days to a few weeks after being contaminated with the bacteria. In some cases, symptoms can take up to 70 days to develop, depending on the individual's immune system and the amount of bacteria ingested.
How long does it take for persons who ingest toxins produced by staphylococcal bacteria to show symptoms?
The toxins are already formed in the food ingested. So the symptoms appear within few hours, say within hour or two of the ingestion of the faulty food.
How long does it take for PID to appear?
It can be days to months or longer for PID to appear.
