Nearly 100% of iodine found in nature is stable, though there are traces of 129I, which is radioactive and only found in insignificant quantities. Like all elements, iodine has synthetic radioactive isotopes.
None of the iridium ordinarily found in nature is radioactive. Like all elements, radioactive synthetic isotopes exist.
No. Naturally occuring indium is not radioactive.
there are many isotopes of indium created artiificially, many of these are radioactive. See wikipedia "Isotopes of indium" for a list.
Yes, Iodine is reactive. =)
No. Irradiation is exposure to radiation.
yes
both a and b are true for iodine and radioactive iodine isotope
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.
Other tissues aren't affected by radioactive iodine because it is a targeted substance.
no
they both glow.
both a and b are true for iodine and radioactive iodine isotope
No: Iodine is not a metal at all, but a nonmetal. It is not necessarily radioactive, but has some radioactive isotopes.
Chlorine and iodine are both non-metals Neither are radioactive They are both made in nature
Iodine-131 is a radioactive isotope of the element iodine.
Thorium is a radioactive metal. Alpha rays irradiation can be dangerous.

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.
Nobelium is not found in nature. It is a synthetic radioactive element.
Thorium is a radioactive metal. Alpha rays irradiation can be dangerous.
Iodine is a non-metallic solid.There are both radioactive and non-radioactive isotopes of iodine. please be more specific.
Iodine tablets are used in a nuclear accident to saturate the thyroid with non radioactive iodine. During a nuclear accident, radioactive iodine is released and the critical organ in the human body is the thyroid gland. Therefore if the thyroid is already full of non radioactive iodine the radioactive iodine can not be absorbed.
