## What does a half life of 8 days mean?

What does it mean that the half life is 8 days. Simply it means that due to the decay half of the material will statistically decay every eight days. if you start with one kilo of iodine 131, eight days later you will have 1/2 kilo, in another 8 days you will have 1/4 kilo and in 8 more days 1/8 kilo, etc.

## What percentage of an iodine-131 sample remains after 30 days?

What percentage of an initial sample of 13153I remains after 30.0 days? We want the percentage of the original sample remaining after 30 days, or, in other words, we want the ratio N(30 days)/No. so the percentage remaining is 7.53%

## How long would it take for the iodine-131 sample to decay to 90% of the sample?

What percentage of an initial sample of 13153I remains after 30.0 days? We want the percentage of the original sample remaining after 30 days, or, in other words, we want the ratio N(30 days)/No. so the percentage remaining is 7.53%

## Is there a half-life of 8 days?

As an example, iodine-131 is a radioisotope with a half-life of 8 days. It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131.

## How many days is a half-life?

You know that the half-life of a radioactive nuclide, t1/2 , tells you the time needed for half of the atoms present in a sample to undergo radioactive decay. In this case, it takes 3.6 days for any sample of this substance to decay to half of its initial mass.

## What does a half-life of one day mean?

half-life. [ hu0103fu2032lu012bfu2032 ] The average time needed for half the nuclei in a sample of a radioactive substance to undergo radioactive decay. The half-life of a substance does not equal half of its full duration of radioactivity.

## What is the ½ life of iodine-131?

What percentage of an initial sample of 13153I remains after 30.0 days? We want the percentage of the original sample remaining after 30 days, or, in other words, we want the ratio N(30 days)/No. so the percentage remaining is 7.53%

## How long does it take for iodine-131 to decay?

Iodine-131 has a half-life of 8.06 days and decays by beta-particle emission to a stable 131Xe.
