What decaying radioisotope produces xenon-131 through beta decay?
Iodine 131 -> Xe 131 + e-
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.
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 long would it take for iodine-131 to decay into xenon?
The half life of Iodine-131 is 8.02 days, that means that say if you had 1 gram of 131I after approximately 8 days there would be only 0.5g left. The other half would have become Xenon-131. After 6 half lives (~48 days in your case) you would only have 1.6% of the original amount left.
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 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
How long does the radiation from plutonium 131 last?
Not plutonium, but iodine-131 !!The half life of 131I is 8,0197 days.
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.
What is the source of iodine-131?
Fission product xenon-131
Is iodine -131 a more stable than barium -137?
Iodine 131 has a half-life of 8.0197 days. Barium has no half-life. So no, Iodine-131 is not more stable than barium-137.
What is iodone-131?
Iodine-131 (not iodone) is a radioactive isotope of iodine: this isotope has important applications in the treatment of thyroid diseases.
