(a)
Interpretation:
The decay constant and half life of the sodium-24 have to be given.
Concept Introduction:
Half life period:
The half life is defined as the amount of time it takes for a given isotope to lose half of its radioactivity.
Where k is the decay constant.
(b)
Interpretation:
Concept Introduction:
Radioactive Law:
The radioactive lawstates that the probability per unit time that a nucleus will decay is a constant independent of time. This constant is called the decay constant and is denoted by
Where
N0 is the number of radioactive nuclei in initial time.
k is the decay constant.
t is the time required to decay.

- 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)? Explain your answer.arrow_forwardTechnetium-99m has a half-life of 6.01 hours. If a patient injected with technetium-99m is safe to leave the hospital once 75% of the dose has decayed, when is the patient allowed to leave?arrow_forward
