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 3.00 days ago?

Radioactive isotope 131I with a physical half-life of 8.1 days, is ingested by patients with healthy or with hyperactive (diseased) thyroids. On two consecutive days, a counter positioned over the gland reads 10000 and 9136 counts per second (cps) for the healthy person and 9500 and 7340 cps for the sick person. What are the biological half-lives of the isotope in the thyroids of the patients?

1. Iodine-131 is an isotope in the treatment of hyperthyrodisim and has an effective half- life of 7.6 days. If a patjent is given a dose of 10.0 mCi, how much radiation remains after 38 days? 2. Phosphorus-32 is a radisotope used to detect certain types of tumors. P-32 has an effective half-life of 14.1 days. If a patient recieves 6.0 mCi, how much radiatjon remains after 169.2 hours?
