Is the iodine-131 from the Chernobyl disaster is still a threat to us today?
You can only say, 23 years later, I-131's radioactivity almost decreases to 1/8 of original radioactivity.
Does all nuclear wastes completely disappear after 50 years?
Not by a long shot. The most radioactive isotopes will decay very rapidly and be safe in much less than 50 years (e.g. iodine-131 with a halflife of about 8 days will be gone in less than 2 months), but less radioactive isotopes will decay so slowly they can be around for hundreds of thousand of years (e.g. plutonium-239 with a halflife of 24400 years will be gone in under 200000 years) to longer than the age of the universe (e.g. uranium-238). Slightly oversimplified, the most dangerous isotopes in nuclear waste tend on average to disappear first with less dangerous isotopes persisting for longer periods.
What is the purpose of nuclear decay?
nuclear decay is when the nucleus of an atom is broken apart. because the number of protons has changed, so has the element. this usually happens with large nuclei, which tend to be more unstable (radioactive) than smaller nuclei.
Is the chernobyl disaster still going?
Its not. The Beta particles (Iodine 131 ) emmited from the diaster will have been spread far and wide now and will also have been less concentrated, so therefore the actual Iodine 131 emmited from the diasaster is of relativly low harm to us, about as much harm as backround radiation.
What is more radioactive than pure uranium?
Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
What is the nuclear equation for the decay of iodine?
Here is the equation for the beta minus decay of iodine-131: 53131I => 54131Xe + e- + ve The iodine-131 undergoes a transformation when a down quark within a neutron in its nucleus changes into an up quark. This change is mediated by the weak interaction, or weak force. The neutron then becomes a proton, and an electron is created and ejected from the nucleus along with an antineutrino.

What decaying radioisotope produces xenon-131 through beta decay?
Iodine 131 -> Xe 131 + e-
How was Iodine-131 formed?
Both iodine-129 and iodine-131 are produced by the fission of uranium atoms during operation of nuclear reactors and by plutonium (or uranium) in the detonation of nuclear weapons. US EPA Link below.
What is the daughter product for the beta decay of iodine-136?
We know that iodine-131 will undergo beta minus decay, and an electron will appear as a result. (An electron antineutrino will also be produced, but we don't want to go there in this topic.)
How many days must elapse for a 0.80 Mg sample of iodine-131 in the thyroid to decay to 0.10 Mg?
The time required is 24.06 days. The half life of iodine 131 is 8.02 days.
What is iodine-131?
Iodine-131 is a radioactive isotope of the element iodine.
Iodine 131 has a half life of 8 days. When will 10 lbs of iodine 131 not be radioactive anymore?
Never. As a simple exponential-decay problem, it can get as small as you want if you're willing to wait long enough, but it never reaches zero.
Is iodine in nuclear bombs?
No. However one of the fission products produced is Iodine-131 and it appears in the fallout. Iodine-131 is a dangerous beta and gamma emitter with a halflife of 8.05 days, it concentrates in the thyroid gland and can selectively kill it or cause cancers in it. Fortunately the halflife is only just over a week, because it then practically disappears in about 5 to 6 weeks. This allows Iodine-131 contaminated food and drink (e.g. fresh milk) to be stored and then safely used when the Iodine-131 has decayed. This also makes it possible to protect the thyroid gland by saturating it with ordinary Iodine (usually as potassium iodide pills) until the Iodine-131 has decayed.
Iodine -131 undergoes radioactive decay to form an isotope with 54 protons and 77 neutrons what type of decay occur in this isotope?
The number 131 on the end shows us the mass of the isotope of iodineIf there are 53 protons, you need to take that away from the mass number to get the number of neutrons(Remember, electrons have such a small mass, we say that they have no mass at all, just to make it easier)131 - 53 = 78So the answer is A
What is the gland doctors image with iodine-131?
The thyroid gland is often imaged using a salt of iodine-131 as this gland has a high uptake of iodine.
Chernobyl Nuclear Power Station in Ukraine disaster affected which human endocrine glands?
The iodine-131 in the fallout poisons the thyroid gland.
What is the source of iodine-131?
Fission product xenon-131
