A radioactive SPECT tracer has a radioactive half-life of 6 hours. If it takes 12 hours to ship the material from the manufacturer to the hospital, how much of the original radioactivity remains in the material when it arrives at the hospital? A radioactive PET tracer has a radioactive half-life of 1 hour. If it takes 12 hours to ship the material from the manufacturer to the hospital, how much of the original radioactivity remains in the material when it...

(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 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...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
