Iridium-192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while lowering the risk of damage to healthy tissue. Iridium-192 is often used in the head or breast. Use the radioactive decay curve of iridium-192 to answer the three questions. If the initial sample is \( 3.50 \mathrm{~g} \). what mass of the original indium-192 remains after 65 days? If the initial sample is \( 3.50 \mathrm{~g} \), what mass of the original iridium-192 remains after 65 days? mass remaining: Incorrect Estimate the half-life of the radioisotope. half-lii How many days would it take for two-thirds of the sample to decay? tin
