A machine called a PET Scanner (for “Positron Emission Tomography”) creates 3-D medical images to help doctors see inside patients without performing surgery. Different radioactive elements such as Fluorine-18, are given to the patient to highlight particular internal features. If the exponential decay of Fluorine-18 has a half-life of about 110 minutes, which of these could be the graph for a treatment of one nanogram of Fluorine-18?
