A patient is adminsitered 20mg of iodine-131. How much of this isotope will remain in the body after 40 days if the half-life for iodine is 8 days? Please show all work in a neat order Thank you.
Iodine-131 is used in medical images for CT scans with contrast. Iodine-131 decay is first order with a half-life of 8.0 days. If a patient is administered a typical dose of 370 mg Iodine, how much Iodine-131 will remain after 24.0 days?
A 0.050 mg dose of iodine-131 was administered to a patient to treat hyperthyroidism. What is the remaining mass after 32.4 days? The half-life of iodine-131 is 8.1 days.
20) A 0.500-g sample of iodine-131 is obtained by a hospital. How much will remain after a period of one week? The half-life is 8.07 days.

A patient ingests 1.58 mg of I-131 (iodine-131), a beta emitter with a half-life of 8.0 days. Assuming that none of the I-131 is eliminated from the person's body in the first 4.0 hours of treatment, what is the exposure (in Ci) during those first four hours? Express with 2 significant figures.Thank you.

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?
A patient is injected with 8.08 uCi of radioactive iodine-131 with a half-life of 8.02 days. Assuming that 90.0% of the iodine ultimately finds its way to the thyroid, what decay rate (or activity) do you expect to find in the thyroid after 23.5 days? decay rate: иСі
