n 14 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 - 50 - 40- 30 20 10 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 Time (days) If the initial sample is 2.50 g, what mass of the original iridium-192 remains after 5 days?

For a radioactive sample with a half-life of about 94 days, storage in a lead lined cabinet for a sufficient length of time assures it will be safe before disposal. A radioactive sample is considered to be safe after 10 half-lives have expired. What percentage of the original radioactivity of the sample remains after this many half- lives? Report answer as a percentage, but do not include the percent symbol. Provide 3 significant digits of precision.
