Interpretation: Calculate the amount of iron-59 left in the sample after
Concept Introduction: Half-life is the time taken by the quantity to reduce to its initial value. In other words, the time taken by the parent nuclides in radioactive decay is half to that of the daughter nuclides.
The total number of half-lives is calculated as:
Here, T is the time required for decay, n is the number of half-lives and
The amount left in the sample is determined by:
Here, N is the amount of sample left after time T and
