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. if a sample of iridium-192 is initially 3.25g and 1.21g remains after 105 days, estimate the half-life of the radioisotope.
