5. Application As a sample of a radioactive element decays into more stable elements, the amount of radiation it gives off decreases. The level of radiation can be used to estimate how much of the original element remains. Here are measurements for a sample of radium-227. Time (h) Radiation Level (%) 100 1 37 2 mtino 4 5.0 0.3
