Technetium-99 has been used as a radiographic agent in bone scans because it can be easily absorbed by human bones. If this nuclide has a half-life of 6.0 hours, how much of a 0.100 mg dose remains in the patient’s body after 1.5 days?
All radioactive decay processes follow first-order kinetics. The half-life of a gamma producing radioactive isotope is 2.4 hours. This isotope is used in a medical scan and enough of the isotope is given such that a heart scan can be done? If 0.75 ng of the isotope is administered, how ng of the isotope remains in the patient after 3.5 days?
14C is a radioactive isotope with a half life of 5.73x10^3 years. Radioactive decay is first order process and the amount of 14C present in an object can be used to determine its age. How long does it take for for 90 % of the 14C in a sample to decompose?
Q#2: What is the half-life of technetium-99m in minutes? Hours? Technetium (chemical symbol Tc) is a silver-gray, radioactive metal. It occurs naturally in very small amounts in the earth's crust, but is primarily man- made. Technetium-99 is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions. Technetium-99 can be found as a component of nuclear waste. Technetium-99m is a short-lived form of Tc-99 that is used as a medical diagnostic tool. As this isotope decays, it...
