The half-life of the radioisotope tritium (H-3) is about 12.32 years. This means that it takes approximately 12.32 years for half of a sample of tritium to decay into helium-3.
A half-life of a radioisotope is the time required for half of a sample to decay. In this case, a 50-g sample becoming 25 g after 18 days indicates that the half-life of the radioisotope is 18 days, as the sample has decreased to half its original amount in that time.
The half-life of the radioisotope Ag-110 is approximately 24.6 seconds. This means that half of the radioactive atoms in a sample of Ag-110 will undergo radioactive decay in that amount of time.
The half-life of the radioisotope Ba-137 is approximately 11.23 minutes. This means that it takes 11.23 minutes for half of a sample of Ba-137 to decay into a more stable element.
The half life of a radioisotope is the time taken for the number of radioactive atoms to decay to one-half. A free neutron has a half life of 10.6 minutes. The half life of carbon 11 is 20.3 minutes. Many isotopes have very short half lives, and many have very long ones.
The half-life of the radioisotope Na-22 is 2.6 years.
It depends on the radioisotope. They do not all have the same half life.
The radioisotope with the shortest half-life among the following options is Polonium-214.
One-half of the original amount. That's precisely the definition of "half-life".
How long it takes for half of a sample to decay to another form.
16 hours.
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.
It is 432 years.
It is 7,380 years.
It is 15.02 hours.
It is 14.6 years.
It is 300,000 years.
