The fraction of radionuclide which will remain after 1 day, 2days, 3 days and 4 days is to be determined. The samples are iron-59 (44.51 days), titanium-45 (3.078h), calcium-47(4.536days) and phosphorus-33 (25.3 days).
According to first order of kinetics:
Here, N and No are final and initial concentrations, is decay constant and t is time.
Here, is half-life time.
