N = No*(1/2)^(t/T1/2)
T1/2 = half life period = 37 min
No = iniital amount
t = time required
N = remaining substance
2.5 = 20*(1/2)^(t/37)
t = 111 min

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 20 Sample remaining (5) SO 30 10 0...
