What is the term for the time required for one half of the atoms of a radioisotope to emit radiation and decay products?
Halflife
Hard water
Hemoglobin
Homeostasis
The correct answer is: Halflife
Radioisotopes are unstable atoms that emit radiation and decay products over time. Half-life refers to the amount of time it takes for half of the atoms in a given sample of a radioisotope to undergo this decay process. This is a specific term used to describe the decay rate of a radioisotope and is not related to hard water, hemoglobin, or homeostasis. Therefore, options B, C, and D are incorrect and do not accurately describe the time required for radioactive decay. Option A, halflife, is the correct term used to describe this process.
