The half life of a radioisotope, or anything with a half life, is the period of time in which any individual component has a 50% chance of undergoing a reaction. Suppose you have 100 atoms of a radioisotope and the half life is 1 day. After a day, 50% (half) of the atoms will have decayed so there will be 50 left. After another day, half of those will decay and there will be 25 left. After another day there will be a 50% chance there will be 13 or more and the same chance of 12 or less and so on. This has serious consequences for radioactive waste. If you start of with a tonne of it and it has a half life of 10,000 years, it will be 60,000 years before there is less than 16 kilograms.

What is the half life of the Radioisotope Na22?
It is 2.6 years.
How much of a sample of radioisotope remains after one half-life?
One-half of the original amount. That's precisely the definition of "half-life".
What is the half lie of a radioisotope?
I assume you mean "half life". That means, how long does it take for half of the atoms in a sample to decay.
What does the half-life of a radioisotope refer to?
The length of time it takes for half of a radioactive sample to decay
What is the half life of the Radioisotope Fe55?
It is 100 years.
How many half lives does it take for half of a radioisotope to dissipate?
It depends on the radioisotope. They do not all have the same half life.
What is the half life of the Radioisotope Am241?
It is 432 years.
What is the half life of the Radioisotope Na22?
It is 2.6 years.
What is the half life of the Radioisotope Na24?
It is 15.02 hours.
What is the half life of the Radioisotope Cd113?
It is 14.6 years.
What is the half life of the Radioisotope Cl36?
It is 300,000 years.
What is the half life of the Radioisotope Co80?
It is 5.27 years.
What is the half life of the Radioisotope Cm244?
It is 18.11 years.
What is the half life of the Radioisotope Ga72?
It is 14.1 hours.
What is the half life of the Radioisotope Ba137?
It is 11.2 years.
