A sample of {:(131),( 53):} I, as iodine ion, was administered to a patient in a carrier consisting of 0.10 mg of stable iodide ion. After 4.00 days, 67.7% of the initial radioactivity was detected in the thyroid gland of the patient. What mass of the stable iodide ion had migrated to the thyroid gland ? ( t_(1 //2 = 8 days.)

One mu g of a radioactive iodine contained in thyroxine is injected into the blood of a patient. How long will it take for radioactivity to fall to 50%, 25% and 10% of the initial value? ( t_(1//2) for ._(53)^(131)I = 8.052 days)

The half life of I""^(131) is 8 day. Given a sample of I""^(131) at t=0, we can assert that

The half life of .^(131)I is 8day. Given a sample of .^(131)1 at t = 0 , we can assert that:

Fallout from nuclear explosions contains ""(131)I and ""^(90)Sr . Calculate the time required for the activity of each of these isotopes to fall to 1.0% of its initial value. Radioiodine and radiostrontium tend to concentrate in the thyroid and the bones, respectively, of mammals which ingest them. Which isotope is likely to produce the more serious long-term effects ? Half-life of ""^(131)I = 8 days, ""^(90)Sr = 19.9 yrs

Iiodine -131 is a radioactive isdotpe. If 1.0 mg of ""^(131)I has an activity of 4.6xx10""^(12) Bq. What is the half-life of ""^(131)I (in days)

The reaction S_(2)O_(8)^(2-) + 3I^(ɵ) rarr 2SO_(4)^(2-) + I_(3)^(ɵ) is of first order both with respect to persulphate and iofide ions. Taking the initial concentration as a and b , respectively, and taking x as the concentration of the triofide at time t , a differential rate equation can be written. Two suggested mechanism for the reaction are: I. S_(2)O_(8)^(2-)+I^(ɵ) hArr SO_(4)I^(ɵ)+SO_(4)^(2-) ("fast") I^(ɵ)+SO_(4)I^(ɵ) overset(k_(1))rarrI_(2) + SO_(4)^(2-) (show) I^(ɵ) + I_(2) overset(k_(2))rarr I_(3)^(ɵ) ("fast") II.
