uppose 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 exposure?

Half-life is that the quantity of your time occupied for half the preliminary material to fragment. Therefore the nuclide with smaller half-life fragments over the nuclide with the lengthier half-life. Therefore nuclide A fragments a lot of manufacturing extra beta emissions than nuclide B. therefore nuclide A harvests the larger emission experience.
