A patient is given 0.055 μg of technetium-99m, a radioactive isotope with a half-life of about 6.0 hours. How long does it take for the radioactive isotope to decay to 2.7×10−3 μg ? (Assume no excretion of the nuclide from the body.) Express your answer using two significant figures.
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.
3. Iodine-131, which is used to treat thyroid cancer, has a half-life of 8.04 days. How much time is required for 68% of the isotope to decay? a. 13 days b. 7 days c. 43 days d. 53 days e. 4 days
Iodine-131 is administered orally in the form of NaI(aq) as a treatment for thyroid cancer. The half-life of iodine-131 is 8.04 days. How much time is required for the activity of a sample of iodine-131 to fall to 17.5 percent of its original value? ____days Nitrogen-13 is used in tracers injected into the bloodstream for positron emission tomography (PET). The half-life of nitrogen-13 is 10.0 minutes. If you begin with 45.1 mg of this isotope, what mass remains after 27.2...
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.
show all work please Roughly 12000 people in a certain country are diagnose a thyroid cancer every year which accounts for 1% of all cancer cases that occurs in women 3 times as frequently as men fortunately thyroid cancer can be treated successfully and many cases with radioactive iodine or I-131 this unstable form of iodine has a 1/2 life of 8 days and is given in small doses measured in milicuries A)suppose a patient is given initial dose of...
