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. 100- 90- 80- 8 70- 60- 50 40- 30- 20 10 10 20 30 40 50 60 70 80 90 100 110 120 130 140 1500 160 170 180 190 Time (days) Sample remaining (%)
