1. 1. Iodine-131 is a radioactive isotope. After 8.00 days, 50.2% of a sample of 131I remains. What is the half-life of 131I? 2. The half-lives of different radioisotopes are given in the table below. If the initial amount of potassium-44 is 9.2 g, how much potassium-44 is left in the body after 44 minutes? 2. 32P is a radioactive isotope with a half-life of 14.3 days. If you currently have 59.9 g of 32P, how much 32P was present...

Question 17 of 20 > 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 70 60 . . Sample...
