. A sample contains 8 g 8 gramsof a radioisotope that has a half-life of 10 years. How much time is required for the sample to decay until approximately 1 g one gramof the isotope remains in the sample? - ANSWER 30 years is correct. If the half-life of the substance is 10 years, then every 10 years the amount of the isotope is decreased by half. Thus, it requires three half-lives, or 30 years, for the isotope to decay until approximately 1 gone gram remains in the sample. 2. Which of the f...
