Understand this objective

Short explanation

Within Different half-lives of radioactive isotopes, this learning objective asks you to evaluate risks and benefits of using radioactive isotopes. Focus on the approved ideas risk, radioactive isotope and connect them clearly to Hazards and uses of radioactive emissions and of background radiation. A strong response should state the relevant particle, radiation, isotope, decay, half-life or nuclear-equation idea, then explain how it answers the exact command word. Avoid swapping nearby concepts such as atomic number and mass number, isotope and ion, alpha, beta and gamma radiation, or contamination and irradiation.
