What is the half-life of iodine-131?
The half-life of iodine-131 is approximately 8 days. This means that it takes 8 days for half of the iodine-131 atoms in a sample to decay into a different element. After another 8 days, half of the remaining iodine-131 atoms will decay, and so on. This property of iodine-131's decay allows it to be used in medical treatments and diagnostic procedures. **
How are Iodine-131, Strontium-90, and Uranium-235 pronounced?
Iodine-131 is pronounced as "eye-oh-dine one-thirty-one", Strontium-90 is pronounced as "stron-tee-um ninety", and Uranium-235 is pronounced as "yoo-rain-ee-um two-thirty-five". **

After how many half-lives has iodine-131 decayed to more than 90 percent?
Iodine-131 has a half-life of about 8 days. After 3 half-lives (24 days), iodine-131 would have decayed to more than 87.5 percent. Therefore, it would take approximately 24 days for iodine-131 to decay to more than 90 percent. **

How many of the 500,000 iodine-131 nuclei have decayed after 3 half-lives?
After 3 half-lives, half of the original nuclei will have decayed in each half-life. So after 3 half-lives, (1/2)^3 = 1/8 of the original nuclei will remain. Therefore, 500,000 * (1/8) = 62,500 iodine-131 nuclei will have decayed after 3 half-lives. **
-
Why was practically nothing of the leaked iodine-131 present one year after the Chernobyl accident?
Iodine-131 has a short half-life of about 8 days, which means it decays rapidly. Therefore, one year after the Chernobyl accident, practically nothing of the leaked iodine-131 was present because it had mostly decayed into stable non-radioactive elements. Additionally, iodine-131 is water-soluble and can be easily washed away or absorbed by living organisms, further reducing its presence in the environment over time. **

When will 78 of a quantity of iodine 131 decay, if the half-life is 8 days?
After one half-life (8 days), half of the original quantity of iodine-131 will decay, leaving 50% or 39 atoms. After two half-lives (16 days), another half of the remaining quantity will decay, leaving 25% or 19 atoms. After three half-lives (24 days), another half of the remaining quantity will decay, leaving 12.5% or 9 atoms. Therefore, it will take approximately 24 days for 78 of a quantity of iodine-131 to decay. **
