(1) Fluorine-18 fluorodeoxyglucose (18FDG) is a radioactive tracer (half life of 1.83 hours) administered to patients who are undergoing PET imaging. This imaging modality, which creates images by detecting the positrons that are emitted when the fluorine-18 undergoes 8+ decay, permits physicians to monitor the metabolism of glucose in the body (a) Write down the decay chain for fluorine-18 when it undergoes β+ decay (b) A patient is given a dose of 18FDG prior to a PET scan to monitor...

Technetium (Tc) is a radioactive element widely used in modern medical imaging (radiology). Its existence was predicted in 1871 by D. Mendeleev, who noticed a gap between then known elements Molybdenum (42) and Ruthenium (44) in the periodic table he envisioned. Technetium used in radiology is a metastable isotope 99Tc that emits gamma photons (half-life T1/2 = 6 h). A solution containing trace amounts of 99Tc (the tracer) is administered to a patient intravenously, and after the isotope uniformly spreads...

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?

The isotope lodine-131 is a radioactive isotope used in industrial and medical applications. It is prepared just before use because it decays rapidly through beta emission. Use the data in the table below to answer the following questions (a) Write the reaction equation. (Note m indicates an excited state of the isotope, which is generally denoted with an asterisks after the symbol, such as X*) (b) What is the rate constant for the decay? Show how you obtained this rate...

Technetium Dosage. Radioactive isotopes are often used for medical imaging. Technetium-99m (Tc-99m) is a particularly popular isotope since it has a short half-life and is easy to make. Also, Tc-99m can be chemically bonded to a number of different compounds and cell types for imaging different parts of the body. Tc-99m has a half-life of 6.02 hours. It decays into Tc-99 by emitting a gamma ray of energy 140 keV. For this problem, assume that Tc-99m is present in the...
