Iodine (regardless of whether it is radioactive or not) tends to concentrate in the thyroid gland. Radioactive iodine can thus lead to thyroid cancer if left unchecked. Fortunately you can generally flush out the radioactive iodine with normal "cold" iodine. We tend to get much of our iodine from salt which is "iodised". Interestingly in some cases when a patient has an overactive thyroid, or indeed in thryoid cancer patients, the thyroid can be chemically ablated by the use of radioactive iodine since it concentrates there naturally.
A nuclear event, such as an accident or war, is likely to produce a lot of radioactive iodine. The thyroid gland concentrates iodine, so any iodine that gets into a person's body is likely to end up there. The potassium iodide tablets provide more iodine than the thyroid can use, so the radioactive iodine is not so likely to be retained in the body. So the potassium iodide reduces exposure to radioactivity. It protects only the thyroid, and it only protects that against radioactive iodine, but it is better than nothing.
Radioactive iodine is taken up by the thyroid gland because it is the only tissue in the body that can absorb and store iodine to make thyroid hormones. Other tissues do not have this ability, so they are not affected by radioactive iodine treatment.
No, irradiation and radioactive iodine are not the same. Irradiation is the process of exposing something to radiation, while radioactive iodine is a form of iodine that emits radiation and is used in medical treatments, such as for thyroid conditions.
Iodine can exist in a radioactive form, known as radioiodine. Radioiodine is commonly used in medical applications, such as imaging and treatment of thyroid conditions. Both forms of iodine can have similar chemical properties, but radioiodine poses additional health risks due to its radioactive nature.
both a and b are true for iodine and radioactive iodine isotope
No, the parathyroid glands are not typically affected by radio-iodine treatment. The main target of radio-iodine therapy is the thyroid gland, as it absorbs and concentrates the radioactive iodine. The parathyroid glands, located near the thyroid gland, are not involved in this process.
No, iodine-127 is not radioactive. It is a stable isotope of iodine, which means it does not undergo radioactive decay and does not emit harmful radiation.
No: Iodine is not a metal at all, but a nonmetal. It is not necessarily radioactive, but has some radioactive isotopes.
Iodine-131 is a radioactive isotope of the element iodine.
A nuclear event, such as an accident or war, is likely to produce a lot of radioactive iodine. The thyroid gland concentrates iodine, so any iodine that gets into a person's body is likely to end up there. The potassium iodide tablets provide more iodine than the thyroid can use, so the radioactive iodine is not so likely to be retained in the body.

Iodine tablets are taken by individuals who have just been or are being exposed to radioactive materials that include radioactive iodine. In nuclear fission reactors, uranium (or sometimes plutonium) fission to create energy. When these fuel atoms split (fission), there are a number of fission products that can result, including a radioactive isotope of iodine. In a reactor accident that includes a meltdown and the release of radioactive fission products into the environment, radioactive iodine can be present. By taking iodine tablets, an individual who is exposed to radioactive iodine that was released in a nuclear reactor accident can avoid having his body absorb this radioactive material. Taking iodine tablets keeps iodine levels in the body high, and the thyroid gland, which absorbs iodine, high. This effectively prevents radioactive iodine from being absorbed and taken up by the thyroid. As absorbing radioactive iodine can lead to thyroid cancer, taking iodine tablets is a good shield against uptake of the radioactive isotope.

no
The answer is simple it is 8 days for iodine-131 but it depends on what isotope you are talking about
No, irradiation and radioactive iodine are not the same. Irradiation is the process of exposing something to radiation, while radioactive iodine is a form of iodine that emits radiation and is used in medical treatments, such as for thyroid conditions.
Basically, radioactive iodine is used to kill cancer cells, and thyroid tissue.
One of the best ways is with FDG-18 PET scans. This is because non-iodine avid disease is often metabolically super-active and concentrates the radioactive glucose rapidly. This then "lights up " on the PET scan.
