What is the half life of radioactive iodine?
The answer is simple it is 8 days for iodine-131 but it depends on what isotope you are talking about
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.
How long does the radiation from plutonium 131 last?
Not plutonium, but iodine-131 !!The half life of 131I is 8,0197 days.
How much of an 80-milligram sample of Iodine-131 would be left after 32 days?
After 32 days, approximately 5 milligrams of the 80-milligram sample of Iodine-131 would be left. Iodine-131 has a half-life of about 8 days, so after each 8-day period, half of the remaining sample will decay.
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.
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 iodine-131?
Iodine-131 is a radioactive isotope of the element iodine.
Radioactive iodine-131 has a half-life of eight days. The amount of a 200.0 gram sample left after 32 days would be -?
12.5 g
A 0.500 M solution of iodine-131 whci has a half-life of 8.0 days is prepared After 40 days how much iodine will remain in 1.0 L of solution Express the result in moles?
0.016 mol
What fraction of iodine 131 is remaining after 4 half- lives?
1/24 = 1/16
How was Iodine-131 discovered?
Iodine-131 was discovered in 1938 by Glenn Seaborg and John Livingood through their research on neutron bombardment of natural iodine. They found that radioactive iodine was produced in the reaction, leading to the discovery of Iodine-131.
