(a)
Interpretation:
For locating brain tumors Arsenic- 74 is (radioisotope) used. A balanced
Concept Introduction:
Radioactive isotopes contain numerous applications. Usually, they are valuable because either one might sense their radioactivity or might utilize the energy released by them. Due to the easy detection of radioactivity of radioactive isotopes, they are effective tracers.
(b)
Interpretation:
If t1/2for As -74 is 18 days, the amount of 120-mg sample remaining after 90 days needs to be determined.
Concept Introduction:
Radioactive isotopes contain numerous applications. Usually, they are valuable because either one might sense their radioactivity or might utilize the energy released by them. Due to the easy detection of radioactivity of radioactive isotopes, they are effective tracers.
(c)
Interpretation:
The volume Ar that should be processed to give a 7.5-mCi dose needs to be determined.
Concept Introduction:
Radioactive isotopes contain numerous applications. Usually, they are valuable because either one might sense their radioactivity or might utilize the energy released by them. Due to the easy detection of radioactivity of radioactive isotopes, they are effective tracers.

- Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. Cl C O Substitution will not occur at a significant rate.
