🤓 Based on our data, we think this question is relevant for Professor Tang's class at USF.
We’re being asked to determine the nuclide that produces the greater radiation given the half-life of Nuclide A and Nuclide B.
Recall that half-life is the time needed for the amount of a reactant to decrease by 50% or one-half.
Radioactive/nuclear decay of isotopes follows first-order kinetics. The half-life of a first-order reaction is given by:
Suppose a person ingests equal amounts of two nuclides, both of which are beta emitters (of roughly equal energy). Nuclide A has a half-life of 8.5 hours and Nuclide B has a half-life of 15.0 hours. Both nuclides are eliminated from the body within 24 hours of ingestion. Which of the two nuclides produces the greater radiation dose?
