Describe the progressive decrease in the activity of a radioactive source over time.
Recall that the Becquerel (Bq) is the standard unit of activity for radioactive isotopes.
Define the half-life of a radioactive isotope as the duration required for half of the unstable nuclei to decay, or for the source's overall activity to halve.
Explain that while individual nuclear decays are unpredictable, the statistical nature of half-life allows for accurate activity predictions across large populations of nuclei.
Perform calculations and interpret graphical representations regarding the radioactive decay and half-life of isotopes.
Describe the biological hazards posed by ionizing radiation, including tissue damage and cellular mutations, and evaluate the necessary safety precautions.
Explain the stringent safety protocols implemented to protect patients and medical personnel from harmful radiation exposure during medical procedures.
Differentiate between the concepts of radioactive contamination and irradiation, and compare the distinct hazards associated with each scenario.
