O Attempt 5
Iridium-192 is one radioisotope used in brachytherapy, in which a radicactive source is placed inside a putient's body to treat
cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while kowering 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
NO.
