Radioactive iodine deposited during external exposure can be removed by washing with warm water and soap. Another type of exposure with greater risk to human health occurs when radioactive iodine is either inhaled or ingested or when substances, such as contaminated food, milk or water, are consumed.
A "dirty bomb" as it has been referred to by the media is a terrorist weapon. It is not an "atomic" bomb. ... If an accident were to occur involving radioactive iodine and evacuation was not possible, potassium iodide could be taken to prevent internal exposure to the thyroid by the radioactive iodine that might be inhaled or ingested following ...
Potassium iodide (KI) blocks uptake of radioactive iodine by the thyroid gland. KI protects only the thyroid from radioactive iodine uptake. KI does not provide protection for any other organs. ... KI is highly effective if taken several hours before inhaled contamination with radioactive iodine.
Tiny amounts of radioactive iodine 131 ingested or inhaled can do lasting and permanent damage to your body because the thyroid will absorb and hold onto the bad iodine. By taking Potassium Iodate tablets, the thyroid will not absorb any of the harmful radioactive iodine 131 because it is inundated with "clean" iodine.
Radioactive iodine used for certain medical tests or the treatment of thyroid disease Tincture of iodine Iodine is also used during the production of methamphetamine.
Potassium iodide (KI) is a chemical compound that can be used to protect the thyroid gland from possible radiation injury caused by radioactive iodine (radioiodine). Some radiological emergencies may release large amounts of radioiodine to the environment.
Nuclear medicine is a division of diagnostic imaging that uses small amounts of radioactive isotopes, such as radioactive iodine 131, to diagnose a variety of diseases and abnormalities in the body. The isotope or radiotracer is injected into a vein, swallowed or inhaled as a gas.
By taking FDA approved potassium iodide prior to exposure of radioactive iodine, your thyroid will become saturated with safe, stable iodine. This will prevent your thyroid's absorption of any additional iodine (radioactive or not) long enough for the radioactive iodine inhaled or ingested to be safely dispersed through the kidneys.

Iodine-131, if inhaled or swallowed, concentrates in the thyroid gland where it can accumulate and cause tumors and cancer within a short period of time. Populations exposed to iodine-131 also have an elevated risk developing thyroid disease.

131 can be inhaled. In the lung, radioactive iodine is absorbed, passes into the blood stream, and collects in the thyroid. Any remaining iodine passes from the body with urine. Long-term (chronic) exposure to radioactive iodine can cause nodules, or cancer of the thyroid.
Feb 20, 2014· Iodine and Radiation. Email. Print. Share. by Dr. Edward Group DC, NP, DACBN, ... After a radiological event, radioactive particles may be inhaled or ingested when food and water supplies become contaminated. The thyroid gland is particularly susceptible to radiation poisoning and immediately protecting this gland from injury is of ...
By taking FDA Approved potassium iodide prior to exposure of radioactive iodine, you will fill up the thyroid with safe, stable iodine, stopping the thyroid’s absorption of any additional iodine (radioactive or not) long enough for the radioactive iodine inhaled or …
Alternatively, intakes of radioactive iodine by inhalation and ingestion can result in exposures of individual organs, most prominently the thyroid in the case of soluble forms of iodine. The organ doses can vary according to biokinetic properties of radioactive iodine.
3 Health Risks of I-131 Exposure. The major health risks associated with exposure to iodine-131 (I-131) involve the thyroid gland, which concentrates this radionuclide. ... because most of the radiation dose is from ingested or inhaled radioiodine, the radiation dose to the thyroid is 500-1,000 times greater than is the largest radiation dose ...
What Causes Thyroid Cancer. Home » Cancer » What Causes Thyroid Cancer. In most cases of thyroid cancer, there is no known cause. ... People living within a 30-kilometer radius of the accident inhaled the radioactive iodine, while people living outside the 30-kilometer radius ingested the radioactive iodine. For reasons not quite understood ...
Radioactive iodine 1 is a byproduct of the fission of uranium atoms. Two processes that lead to the creation of radioiodine are the fission of uranium as fuel in nuclear reactors and its use as an explosive material in atomic bombs.
bloodstream, inhaled or swallowed. The radiotracer travels through the area being examined and gives off energy in the form of gamma rays which are detected by a special ... Radioactive Iodine (I-131) Therapy page for instructions on how to prepare for the procedure.

Public Health Service for Nevada Operations Office Atomic Energy Commission Project Director Morgan S. Seal, USPHS Deputy Director E. L. Fountain, USA, VC May 20, 1964 Department of Health, Education, and Welfare Public Health Service
The nuclear accident at the Chernobyl atomic power station on April 26, 1986, exposed millions of people with healthy thyroid glands to excessive levels of radioactive iodine. People living within a 30-kilometer radius of the accident inhaled the radioactive iodine, while people living outside the 30-kilometer radius ingested the radioactive ...
The control group inhaled distilled water. The results showed an over trend for lower accumulation of radioactive iodine in the parotid and submandibular gland salivary glands, and stimulation of faster salivary secretion in the parotid salivary glands after the treatment to help washout the accumulated radioactive iodine. (28)
The rest passes from the body in urine. Airborne I-129 and I-131 can be inhaled. In the lung, radioactive iodine is absorbed, passes into the blood stream, and collects in the thyroid. Any remaining iodine passes from the body with urine. In the body, iodine has a biological half-life of about 100 days for the body as a whole.

In this paper, the dose assessment for the iodine inhalation exposure in 19 aerosol sizes and three gas/vapor forms at three levels of thyroid uptake, was performed. ... where f i * (t) is the amount of radioactive substance in the compartment i at time t. K ij (t) ...
The decay of this gaseous offspring of uranium can produce radioactive isotopes of bismuth, polonium and lead, which once inhaled attach themselves to the lungs. As a result it is the inhalation of radon which is the principal source of natural internal exposure.
These compounds contain iodine, but not in the iodide form. However, since they may be ultimately metabolized or break down to radioactive iodide, it is common to administer non-radioactive potassium iodide to ensure that iodide from these radiopharmaceuticals is not sequestered by the normal affinity of the thyroid for iodide.
Radionuclide Basics: Iodine. Iodine (chemical symbol I) is a chemical element. ... Beta-emitters are most hazardous when they are inhaled or swallowed. ... Once inside the body, radioactive iodine will be absorbed by the thyroid gland, potentially increasing the risk for thyroid cancer or other thyroid problems.
Iodine 129 decays into radioactive Xenon 129 sometime during its 16 million years. It is important to realize that radioactive Iodine does not disappear. It transmutes as it decays into other radioactive elements, such as radioactive Xenon gas, which can be inhaled easily, and which causes lung cancer.
