Question
8. A nuclear stress test utilizes a gamma-emitting radioisotope such as thallium-201 to
follow the flow of blood through the heart. Th first-order rate constant for the decay of
thallium-201 is 9.5 x 10 3 hr . Calculate how long it takes for a 0.50 M solution of
thallium-201 to disintegrate to 0.15 M.
