Each statement that follows refers to a comparison between two radioisotopes, A and X. Indicate whether each of the following statements is true or false. (a) If the half-life for A is shorter than the half-life for X, A has a larger decay rate constant. (b) If X is “not radioactive,” its half-life is essentially zero. (c) If A has a half-life of 10 yr, and X has a half-life of 10,000 yr, A would be a more suitable radioisotope to measure processes occurring on the 40-yr time scale.
