The iodine isotope 13153I is used in hospitals for diagnosis of thyroid function. If 772 μg are ingested by a patient. I only need help for part c but I would appreciate it if you could show how you did parts a and b. :) A. Determine the activity immediately. Use Appendix F in the textbook. ∣dNdt∣∣0 = 3.55×1012 decays/s B. Determine the activity 1.00 h later when the thyroid is being tested. ∣dNdt∣∣ = 3.54×1012 decays/s C. Determine the activity...

The iodine isotope 13153I is used in hospitals for diagnosis of thyroid function. 822 μg are ingested by a patient. The half-life the iodine isotope 13153I is 8.0207 days and mass is 130.906 u. Determine the activity immediately after ingestion. Determine the activity 1.00 h later when the thyroid is being tested. Determine the activity 3.0 months later. Suppose that each month has 30 days.

Iodine-131 is an isotope of iodine (Z = 53) used for the treatment of hyperthyroidism, as it is readily absorbed into the cells of the thyroid gland. With a half-life of 8 days, it decays into an excited Xenon-131 atom (Z = 54). Part A What type of radioactive decay occurs in this process? Gamma decay Beta decay Alpha decay Electron capture SubmitMy AnswersGive Up Correct Part B The related isotope iodine-125 is used in brachytherapy. In what way does...

The greatest concentration of iodine in the body is in the thyroid gland, so radioactive iodine-131 is often used as a tracer to help diagnose thyroid problems. Suppose the activity of 131I in a patient’s thyroid is initially 1.85 × 106 Bq. 131I decays via beta radiation with an average energy of 180.0 keV per decay. Calculate the absorbed dose in sieverts the patient’s thyroid receives in the first hour of exposure. Assume that half of the radiation is absorbed...

Iodine 131 is a radioactive isotope that decays as time passes. The function M(t) = 200e-0.093t gives the mass of Iodine 131 remaining in the sample measured in grams in terms of t number of days since the samples mass was originally measured. a) What was the initial mass of Iodine 131? b) What is the one days decay factor and what is the one day percent change? c) How long will it take for the sample to decay such...

Part A How long does it take for the radioactive isotope to decay to 6.0×10−4 μg ? (Assume no excretion of the nuclide from the body.) Part B A radioactive sample contains 1.70 g of an isotope with a half-life of 3.6 days. What mass of the isotope will remain after 5.8 days? (Assume no excretion of the nuclide from the body.) Part C A mammoth skeleton has a carbon-14 decay rate of 0.46 disintegrations per minute per gram of...
