What Are the Effects of Acute Radiation Syndrome in the Body

Acute Radiation Syndrome or radiation poisoning may be fatal and longer exposure to high levels of radiation without protection often cause death.

Acute Radiation Syndrome (ARS) is the medical term for radiation poisoning or radiation sicknesses from exposure to radiation toxic. Severe exposure for a longer dosage may be attributed to immediate death. Though the symptoms may be similar to whatever dosage of radiation levels one received during the time of exposure. A dose of greater than 50 rads is very fatal and often end in death. No medical treatment is effective when the radiation reach its normal limit. They are many types of radiation syndrome experience that would endanger the lives and pose threat to human evolution. In succession even the environments are deeply affected thereby increasing the mortality rates and a decline of the economy of those countries affected by explosion of radiation emission.

They are four stages of Acute Radiation Syndrome that deeply affect the different external and internal organs resulting to excessive burning of skin tissues, brain damage and blood system damage. Longer term exposure to large doses may result to:

Cerebrovascular syndrome:

It happens when the amount of exposure to radiation exceeds the dosage of (30 Gy) that is often fatal causing immediate death. The length of survival chance is very slim and the patient would die within 1 or 2 days. Patients would experience increase body tremors, seizures, ataxia and brain clot or cerebral edema.

GI Syndrome:

It happens when the amount of exposure to radiation reaches a level of 6 to 30 Gy. In a matter of 4 to 5 days it results to the death of the lining of the mucosal tissues. Thereby resulting to symptoms of nausea, diarrhea and vomiting that could lead to electrolyte imbalance causing dehydration, vascular collapse and diminished plasma volume. Patients would stools appear black a signs of the extreme damges to the intestines tissues thatmay lead to sepsis and bacteremia. Those patients exposed to the radiation levels of >10 Gy would also experience cerebrovascular syndrome indication of a lethal dose.

Hematopoietic syndrome:

It happens upon exposure to the amount of radiation of about 1 to 6 Gy manifested by generalized pancytopenia. The mild prodromal symptoms would occur within 1 to 6 hours lasting up to 24 to 48 hours.

The organs deeply affected are the bone marrow cells resulting in lymhopenia wherein the immunity system is affected thereby affecting the normal regulation of the circulatory system in the body. The assymptomatic period durin the latent phase would last upt o 4 and ½ weeks after the 1 Gy dose radiation exposures. The patients become more vulnerable to lot of infection when the antibody protection is not working.

Mucosal bleeding result from thrombocytopenia develops within 3 to 4 weeks and would last up to 3 to 4 weeks. The accompanying symptoms would cause the patient to develop anemia when the white blood cells numbers exceeds the number of the red blood cells. Those who survive the debilitating acute radiation syndrome acquire different types of cancer affecting the thyroid, kidney, and liver, intestine and suffer from leukemia.

Pregnant women have the tendency to be more susceptible to bear child with hydrocephalus and fetus subject to mutation. The external organs suffer from erythema, intense reddening, blistering, ulceration and dryness. Alopecia and damage to the sebaceous and sweat glands are also evident with accompanying fibrosis, decreased or increase pigmentation, ulceration or necrosis of the exposed tissue.
