Interpretation:
The mass of technetium-99m will remain when it arrives at the hospital has to be given.
Concept Introduction:
The radioactive law states 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
Radioactive decay law,
Where N is the number of radioactive nuclei remaining after time t.
N0 is the number of radioactive nuclei in initial time.
k is the decay constant.
t is the time required to decay.
