What is the half-life of bismuth-214?

What data do we have about the half-life of bismuth-214?

What is the relationship between the mass of a sample of bismuth-214 and its half-life?

Answer

The half life of bismuth-214 is 19.7 minutes.

Bismuth-214 Half-life Explanation:

Bismuth-214 has a half-life of 19.7 minutes. This means that it takes 19.7 minutes for the mass of a sample of bismuth-214 to decrease to half of its original value.

Half-life is a property of radioactive substances, and it is the time required for half of the radioactive nuclei in a sample to undergo radioactive decay.

In the case of bismuth-214, if 34.7 minutes are required for the mass of a sample of bismuth-214 to fall to 29.5 percent of its original value, then based on the decay constant λ formula, the half-life is calculated to be 19.7 minutes.

Understanding the half-life of bismuth-214 is crucial in various scientific and medical applications, such as radiometric dating and cancer treatment.
