You are considering purchasing two homes that sit on land that contains recently buried radioactive waste. You stand to get a great deal, and plan to use your knowledge of chemistry to assess the risk! One property has a sizeable amount of Iodine-131 buried (I-131 half-life = 8 days), while the other has a sizeable amount of Iridium-192 buried (Ir-192 half-life = 74 days). a) Calculate the percentage of the original amount of each of these samples that will be present on the property after 2 weeks (14 days) b) Assuming that neither of these isotopes will decay into radioactive byproducts - and that the decay of I-131 and Ir-192 are equivalent in their risk to living organisms - which property (if any) should you consider purchasing
