WebRadioactive Half-Life Formula Questions: 1. If the half-life of 100.0 grams of a radioactive isotope is 8 years, how many grams will remain in 32 years? Answer: To answer this question, there is no need to solve for the radioactive decay equation. If 32 ÷ 8 = 4, then the material will go through 4 half-lives. 6.25g. 2. WebReal World Example --- Iodine -131. Iodine-131 is a radioactive substance and has a pretty short half life of only 8 days. Graph 3, below, represents the graph of its half life. If 30 grams is given to a patient, then, how much of the substance is left after 8 days ? You can see, on Graph 3, that 1 half life is the point (1,15).
