     The purpose of RABEX: The Radiation and Cancer Biology Practice Examination is to supplement the training of radiation oncology residents by providing an educational resource to help guide residents in the study of cancer and radiation biology. It is anticipated that The Radiation and Cancer Biology Practice Examination will also assist residents and board eligible radiation oncologists in preparation for the cancer and radiation biology section of the cognitive exam administered by the American Board of Radiology for certification in radiation oncology.

     Well into its second decade of existence, RABEX continues to be a unique and important educational tool for the certification and continuous education of residents and senior radiation oncologists. The present edition of RABEX follows the original goals defined in the 1990ís by Drs. J. D. Chapman, S. Shahabi, L. R. Coia, and B. Corn. However, due to the increase in knowledge in the field of biology and the rapid development of electronic distribution of information, RABEX needed to be updated to match these challenges. The ultimate goal of the present edition is to maintain its level of excellence with relevant updates in topics and contents.

     The topics included in the RABEX practice examination continue to be based upon those listed by the American Board of Radiology for the cognitive exam in radiation and cancer biology. Also, the number of questions in each section reflects the ABR's relative weight for each topic. Therefore, this practice examination provides guidance for residents and senior radiation oncologists in their preparation for the initial radiation oncology certification examination as well as to demonstrate cognitive expertise in radiation biology required for maintenance of certification.

     The exam consists of 200 multiple choice questions in, ABR format:
Molecular mechanisms of DNA damage and repair; chromosome and chromatid damage; mechanisms of cell death; cell survival models; LET and RBE; oxygen effect; repair at the cellular level; tumor microenvironment; cell and tissue kinetics; molecular signaling; cancer biology; total body irradiation; clinical and mechanistic responses to radiation of normal tissues; therapeutic ratio; time, dose and fractionation; brachytherapy; alternative radiation modalities; chemotherapeutic agents; radiosensitizers, bioreductive drugs and radioprotectors; hyperthermia; radiation carcinogenesis; heritable effects of radiation; radiation effects in the developing embryo; radiation protection, Molecular Techniques used in Radiation and Cancer Biology, & Molecular Imaging.

      The answer, along with an explanation and appropriate reference, will be provided for each question.
