(a)
Interpretation:
A balanced equation for the beta decay of sodium-24 nucleus 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.
(b)
Interpretation:
For 15 h half-life time of Na-24, the mass of 84 mg sample remaining after 2.5 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 of radioactive sodium-24 that must be given in a 6.5-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.
