Why is a radioactive curve not a smooth curve?
radioactive curves are not smooth curves because of the points you will be given to plot on the graph sheet
How are patients given radioactive substances for visualization?
by mouth or intravenously
If water containing radioactive oxygen were given to plants in what end product of photosynthesis would you find radioactivity?
Yes, you will find radioactivity as one of the end product of photosynthesis if the water containing radioactive oxygen is given to plants.
Why is Radioactive decay is said to be random?
The underlying truth in radioactive decay is that on an individual basis, no unstable atom will have a predictable time until it will decay. We understand and characterize the decay of radionuclides on the basis of statistical analysis. Only by looking at a large number of atoms of a given isotope of a given element and counting the decay events over time can we quantify the decay rate. The term half-life is used to state (based on the statistics) when half of a given quantity of a substance will have undergone radioactive decay. Note that atoms are incredibly tiny things, and even if we have very tiny quantities of a given radioactive material, we'll have huge numbers of atoms of that material in the sample. The larger the number of atoms of material and the longer we count the decay events, the more accurate our half-life value will be. Having said all that, no one can predict when a given atom of any radionuclide will decay. Each is different, and that is the basis for the random nature of nuclear or radioactive decay.
How do they administer the dye in a thyroid nuclear medicine scan?
Most often, the patient is given the radioactive substance in the form of a tasteless liquid or capsule. It may be injected into a vein (intravenously) in some instances.

What do you mean by radio active half life?
In any radioactive substance, individual atoms will decay randomly. There is no way to know exactly when any particular atom will decay. On average and in broad terms, however, we can predict how many atoms will decay in any given period of time, and this time varies with the isotope involved. The "half-life" of a radioactive substance is the time that it will take for half of the atoms to decay. Very radioactive isotopes will decay quickly and will have very short half-lives; slightly radioactive isotopes will decay slowly and have long half-lives.

what is the amount of mass given in a given volume of air?
Density of substance = mass of substance / volume mass of substance = density x volume
The amount of mass in a given volume of a substance?
That is called the density of the substance.
