By the analysis of graph, the mass of technetium-99m present at 200 minutes and 400 minutes is to be determined. The half-life of technetium-99m in minutes and in hours is to be calculated. The remaining amount left in the patient’s body after one day is to be estimated. Concept Introduction: A half-life is the amount of time taken for half of a substance to undergo some specified process. Technetium-99m is an isomer of technetium-99 which is widely used as a nuclear medicine.
