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- (5) Jaung 80- 70. half-life: time: 60- 50- 40- RR2 30- 20 70 80 90 100 110 150 130 140 150 160 170 10 10 Time (days) If the initial sample is 2.50 g. what mass of the original iridium-192 remains after 35 days? 10- mass remaining: 0 19 20 30 30 NI Estimate the half-life of the radioisotope. How many days would it take for two-thirds of the sample to decay? 8 days days Iridium-192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat cancer.
