Nuclear Radiation Iodine

Iodine in the form of iodide is made into two radioactive forms of iodine that are commonly used in patients with thyroid diseases.

Medicina nuclear guanabara marcacao exames. Iodine 131 131 i i 131 is an important radioisotope of iodine discovered by glenn seaborg and john livingood in 1938 at the university of california berkeley. In this test you will ingest a very small dose of radioactive iodine. Iodine 129 as an extinct radionuclide.

I 123 harmless to thyroid cells and i 131 destroys thyroid cellsthe radiation emitted by each of these forms of iodine can be detected from outside the patient to gain information about thyroid function and take pictures of the size and location of thyroid. Iodine pills can protect health after nuclear radiation. Radioactive iodine testing depending on the dose radioactive iodine can kill a portion or all of your thyroid.

Your doctor will order a radioactive iodine uptake and scan to determine your dose the cause of your hyperthyroidism and information about your thyroid tissue. Iodine is often used to protect the thyroid from the effects of radiation as we were clearly reminded during the nuclear disaster at fukushima in 2011. Radioisotopes of iodine are called radioactive iodine or radioiodinedozens exist but about a half dozen are the most notable in applied sciences such as the life sciences and nuclear power as detailed below.

The rai collects mainly in thyroid cells where the radiation can destroy the thyroid gland and any other thyroid cells including cancer cells that take up iodine with little effect on the rest of your body. The chernobyl miniseries recently premiered on hbo giving many an up close look at what happened when the chernobyl. It is associated with nuclear energy medical diagnostic and treatment procedures and natural gas production.

Nuclear accidents are still fortunately rare enough that there havent been very conclusive studies on the results of radioactive iodine exposures. For example uranium has thirty seven different isotopes including uranium 235 and uranium 238. Of iodine and only one is not radioactive iodine 127.

But after chernobyl the most significant. There are 37 known isotopes isotopea form of an element that has the same number of protons but a different number of neutrons in the nucleus giving it a different atomic mass. Iodine chemical symbol i is a chemical element.

It has a radioactive decay half life of about eight days. Mentions of radioiodine in health care contexts refer more often to iodine 131 than to other isotopes. While iodine protects against radiation poisoning of the thyroid its radioactive state has also proven a useful emergency medical tool.
