Quarks, Leptons, Fermions, and Bosons-The Subatomic World of Radiation Therapy

Quarks, Leptons, Fermions, and Bosons-The Subatomic World of Radiation Therapy James S. Welsh Oncologist 2006; 11: 62-64 Author Information and Disclosures Target Audience: Physicians who wish to advance their current knowledge of clinical cancer medicine in symptom management and are involved in providing patient care in a cancer care environment. Method of Physician Participation: Read course materials, complete course quiz and evaluation form (optional). Learning Objectives After completing this course, the reader should be able to: Describe where the commonly prescribed forms of radiation such as photons, electrons, and protons fit into the grander scheme of subatomic particles. Discuss the categories of subatomic particles prescribed in radiation oncology such as bosons, fermions, leptons, quarks, baryons, hadrons, and mesons. Categorize fundamental particles as fermions or bosons based on their spin. Categorize particles as leptons or quarks based on their types of interactions. Categorize hadrons as baryons or mesons based on their quark composition. The NIH/FAES designates this educational activity for a maximum of 1 AMA PRA Category 1 Credits™. Physicians should only claim credit commensurate with the extent of their participation in the activity.
