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.
262 / 2 is equal to 131.
8.02 days
Not plutonium, but iodine-131 !!The half life of 131I is 8,0197 days.
Iodine-131 has a half-life of about 8 days.
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.
1/24 = 1/16
The answer is simple it is 8 days for iodine-131 but it depends on what isotope you are talking about
About 2 and a half hours.
The time required is 24.06 days. The half life of iodine 131 is 8.02 days.
130 or 131 depending if it's a leap year.
Iodine 131 is radioactive and has a half life of about 8 days. After 32 days there would be approximately 5 milligrams remaining
