If the whole body is exposed to, say, 1,000 rads within a short time, this could be fatal. It also depends on the area of the body that is exposed. Very low doses of radiation are all around us all the time, and they do not have any effect. Hematopoietic stem cells, or bone marrow cells, are the cells that all other blood cells derive from. Recovery or death: There may be a slow recovery, or the poisoning will be fatal. Overt stage: Depending on the type of exposure, this can involve problems with the cardiovascular, gastrointestinal, hematopoietic, and central nervous system (CNS) Latent stage: Symptoms seem to disappear, and the person appears to recover Prodomal stage: Nausea, vomiting, and diarrhea, lasting from a few minutes to several days Symptoms of severe radiation poisoning will normally go through four stages.

damage to the cells that line the digestive tract.

Symptoms depend on the dose, and whether it is a single dose or repeated. The signs and symptoms of acute radiation poisoning are: Radiation sickness can be acute, happening soon after exposure, or chronic, where symptoms appear over time or after some time, possibly years later. The dose is received in a short time, usually within minutesДЄ person who experiences an atomic explosion will receive two doses of radiation, one during the explosion, and another from fallout, when radioactive particles float down after the explosion.

The dose affects the whole body, or most of it, and is able to penetrate to the internal organs.A person receives over 70 rads from a source outside their body.From 200 to 1,000 rads: The person may become seriously ill.ДЄccording to the Centers for Disease Control and Prevention (CDC), radiation sickness, or acute radiation syndrome (ARS) is diagnosed when:.From 30 to 200 rads: The person may become ill.Below 30 rads: Mild symptoms will occur in the blood.They are used in a similar way, but 1 rad is equivalent to 0.01 Gray. Some of the units used are Grays, Sieverts, rems, and rads. Radiation dosage can measured in various ways. The more often a person is exposed, the greater their risk of health problems. When radiation damages cells, it is irreversible. While one small dose is not dangerous, repeated small doses could be.ДЄ sudden, short, low dose of radiation is unlikely to cause a problem, but extended, intense, or repeated doses can be. The technician, meanwhile, will leave the room when taking the image. Nevertheless, the parts of the body that are not being x-rayed will be shielded with a lead apron to prevent unnecessary exposure. Whether or not it becomes dangerous depends on:ДЄ dose of radiation from a single x-ray is not normally harmful. Normally, radiation occurs in a safe environment. They can harm and help people in different ways, and some are more dangerous than others.

Different radioactive substances have different characteristics. Radiation poisoning happens when a radioactive substance gives off particles that get into a personвЂ™s body and cause harm. Share on Pinterest Radiation has many uses, but it can be dangerous if it is not managed correctly.
