Questions and Answers

What is the primary purpose of irradiating a target material in a nuclear reactor to produce radionuclides?

  • To induce nuclear reactions and form the desired radionuclide (correct)
  • To reduce radiation exposure for operators
  • To destroy the stable isotope in the target material
  • To speed up the chemical separation process

How do cyclotrons differ from nuclear reactors in producing radionuclides?

  • Accelerating charged particles to induce nuclear reactions (correct)
  • Using stable isotopes as target materials
  • Utilizing chemical separation for radionuclide production
  • Performing synthesis in shielded facilities

What is the purpose of radionuclide harvesting after irradiation of the target material?

  • To extract and harvest the produced radionuclide (correct)
  • To eliminate radiation exposure
  • To increase chemical impurities
  • To speed up the synthesis process
