D)gamma radiation
E)an omega particle

Question

Quizplus · Accepted Answer

The most commonly used isotopes in medicine are radioisotopes, such as technetium-99m and iodine-131, which emit beta particles. Beta particles are also emitted by many biologically important isotopes, such as carbon-14 and phosphorus-32. While gamma radiation is also emitted by some isotopes, beta particles are more common and have a greater biological impact. Therefore, C is the best choice as it accurately reflects the type of radiation emitted by both commonly used and biologically important isotopes.
