(a)
Interpretation:
A balanced
Concept Introduction:
Radioactive isotopes contain numerous applications. Usually, they are valuable either since 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:
The mass of Ir-192 remaining after 5 30-day month needs to be determined.
Concept Introduction:
Radioactive isotopes contain numerous applications. Usually, they are valuable either since 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 activity remaining after 10 30-day month for the sample of Ir-192 needs to be determined, if the initial activity of the radioactive isotope is 36 Ci.

- A sample of rock was found to contain 8.23 mg of rubidium-87 and 0.47 mg of strontium-87.. (a) Calculate the age of the rock if the half-life of the decay of rubidium by emission is 4.71010 y. (b) If some S3887r was initially present in the rock, would the rock be younger, older, or the same age as the age calculated in (a)?
