The half-line of a radioisotope is the amount of time it takes for?

A. The age of an artifact to be calculated.

B. Half the sample to decay.

C. Detectable radiation to be absorbed by a sample.

D. All the sample to decay

(b) The half-life of a radioisotope is the amount of time it takes for the amount of time it takes for half the sample to decay.

A radioisotope decays and changes to an alternate element at a consistent rate. The rate is estimated in a unit called the half-life. This is the time span it takes for half of a given measure of the radioisotope to decay. This rate is dependably the same for a given radioisotope.
